What is Depression?
Depression is a common but serious medical condition that affects mood, thinking, and daily functioning. It is more than feeling sad for a day or two. It changes how your brain and body work, especially the chemicals that help control emotions and motivation.
Feeling low sometimes is normal, especially after a loss, stress, or disappointment. But clinical depression causes ongoing low mood or loss of interest that stays for weeks or months. It can cause symptoms like constant tiredness, trouble concentrating, changes in sleep or appetite, and feeling emotionally weighed down. Many people feel like they are stuck in a fog, cannot find motivation, or that everyday tasks take too much energy. These feelings can make work, school, relationships, and routines much harder.
Depression is not a sign of weakness. It is a medical condition, and it can be treated. Factors such as genetics, stress, personality, health, brain chemistry, and past experiences can play a part. Understanding depression and noticing its effects early is the first step toward feeling better and getting the right support.
Types of Depression
Although people often use the word depression in a general way, there are several recognised forms. Each one has its own features, but all involve ongoing mood changes that affect daily life.
1. Major Depressive Disorder (MDD)
Major depression involves a persistent low mood or a loss of interest in almost everything. Symptoms last at least two weeks or more and affect daily functioning. People may feel very tired, struggle to get out of bed, lose motivation, or feel mentally slowed. This type may happen once or come back in episodes over time. A doctor diagnoses it based on symptom patterns and impact, not personality.
2. Persistent Depressive Disorder (PDD / Dysthymia)
This type is a long-term low mood that lasts for months or even years. It feels less intense than major depression, but stays around most days. People describe it as a constant heaviness or lack of spark. They often function through the day but feel drained and emotionally flat. It can feel like “this is just who I am,” but it is still treatable.
3. Postnatal Depression
Postnatal depression happens after having a baby. Hormones, sleep disruption, and emotional or physical recovery pressure can trigger this type. Symptoms go beyond normal exhaustion and may include crying often, feeling detached from the baby, low mood, or overwhelming fatigue. GP support is essential for safety and well-being.
4. Seasonal Affective Disorder (SAD)
SAD happens during certain seasons, most often winter. Less sunlight can affect mood-regulating chemicals in the brain. Symptoms usually lift when the seasons change. People may sleep more, crave carbs, withdraw socially, or feel mentally slow. This type comes back in cycles and responds well to treatment.
5. Depression with Anxiety Distress
This type includes features of both depression and clinical anxiety. People feel low, unmotivated, emotionally flat, and also tense or overwhelmed by worry. The depression symptoms often dominate, but both are treated together with your GP.
6. Bipolar Depression
This is the depressive phase of bipolar disorder. It involves low mood episodes but also includes a history of manic or high-energy periods. It must be treated differently from other forms, often with shared GP and specialist support.
Common Symptoms of Depression
Depression symptoms show up in three main areas: physical, emotional, and behavioural, matching the structure of anxiety, but adapted correctly to the condition.
Physical Symptoms
These are often the first signs people or families notice:
- Feeling tired most days
- Sleeping too much or too little
- Changes in appetite (more or less than usual)
- Weight changes over weeks or months
- A sense of moving or thinking more slowly
- Headaches or body aches without a clear cause
- Low energy even after resting
- Feeling physically heavy or drained
- Weakened immune response, causing frequent illness (long-term sign)
- Dry mouth or low hydration from inactivity or oversleeping
These physical sensations can feel worrying. Many people think it is stress, tiredness, or a physical illness, but a GP can identify the cause early and guide treatment.
Emotional Symptoms
Unlike conditions that are mostly silent, depression strongly affects emotions. These include:
- Feeling sad, low, or empty most days
- Feeling hopeless or like things will not improve
- Feeling overwhelmed by small tasks or decisions
- Irritability or emotional sensitivity
- A sense of emotional numbness or disconnection
- Feeling detached from yourself or daily life
- Negative or self-critical thoughts that feel automatic
- Loss of joy in things you used to enjoy
- Feeling like a burden, even when you are not
- Difficulty switching off low mood or mental fog
These symptoms can affect confidence, motivation, and self-worth, but they can all improve with the right support.
Behavioural Symptoms
These are patterns that develop because depression drains energy and motivation:
- Avoiding social events or group activities
- Withdrawing from friends or family
- Difficulty focusing or staying on task
- Stopping routines like sports, school activities, or hobbies
- Overthinking or replaying past conversations
- Sleeping to escape instead of resting for health
- Needing reassurance but feeling doubtful when receiving it
- Missing appointments or follow-ups
- Struggling to start the day or with structured tasks
- Avoiding emotional conversations due to a lack of mental capacity at the time
These behaviours may give short-term relief but can make depression stay longer without structured treatment.
Risk Factors
You may be more at risk if:
- You have a family history of depression or anxiety
- You have been through trauma, abuse, or long-term stress
- You live with chronic health issues or pain
- You have poor or disrupted sleep long-term
- You use alcohol, caffeine, or nicotine to cope
- You often internalise feelings instead of seeking early support
- You feel socially isolated or unsupported
Treatment Options for Depression
Depression is treatable, and many people recover well with the right plan. At HelloGP, care is personalised based on symptoms and lifestyle.

Cognitive Behavioural Therapy (CBT)
The most effective and widely recommended treatment. CBT helps identify and reshape negative thinking, build motivation strategies, and make daily tasks feel possible again.

Helps people reconnect with meaningful parts of life even when the mood is recovering gradually.
Talk-based and Person-centred Therapy
Provides a safe space to express thoughts without judgment.
Behavioural Activation Therapy
Focuses on rebuilding daily action and motivation bit by bit.

2. Medication
A GP may recommend medication when symptoms are moderate to severe or affecting daily life.
Common options include:
- SSRIs (Selective Serotonin Reuptake Inhibitors)
- SNRIs (Serotonin–Norepinephrine Reuptake Inhibitors)
- Other medicines suited to long-term or specific depression types
- Short-term support medicines (when necessary and monitored closely)
- Medication may be temporary or long-term depending on medical need.
3. Lifestyle and Self-Management
Sometimes structured daily changes support recovery faster:
- Regular walks or light exercise

- Reducing alcohol and nicotine coping habits
- Balanced meals, even when appetite shifts
- Drinking more water
- Speaking to supportive people
- Spending time outdoors
- Journaling small thoughts or setting timed check-ins with yourself
