Gravity Falls Fanfiction

Hi, I'm looking for a gravity falls fanfiction I believe that I read some time in 2020 (Possibly 2021, but i dont think so) pretty sure it was on Archiveofourown

What I remember from the fic:

It was centered around dipper

It took place in the future (dipper and Mabel were adults)

Dipper was back in gravity falls. i think the reason he was in gravity falls was because he had tried to commit suicide (PTSD related reasons i think) and the people around him thought it would be a good idea for him to get away.

Dipper used to have a roommate. the roommate was worried about dipper because of all the nightmares dipper used to have

Mabel had a girlfriend (maybe fiancé??) and i think they were on a vacation in Europe. I think the girlfriends name was something like Sam or Samantha

Wendy found out dipper kept a gun in the glovebox of his car

I think near the end of the story Dipper was hallucinating Bill Cipher and he shot at the hallucination. One of the other characters (I don't remember who) ran up the stairs thinking that Dipper had shot himself.

Thats all i remember plot-wise

Im sure it had mutiple chapters.

The word count would've been over 8000 words at the bare minimum, and probably no more than 80000 words (I know, wide range. i dont have the best memory :P)

Ive spent the past few days looking for it, but no dice. i really need help with this.
