Text Issues of the Tiny Kind

Im using Photoshop CS and whenever I make an Icon (100x100) and I try and put in text it shrinks it, Even if I set it to a larger size its still tiny, like unreadable tiny. Its like its proportioning it to the size of the icon, if that makes sense. Im tired. So to get it somewhat readable I need to set the font in the 100's which I really shouldnt have to do. And even when I do that its still all messed up because its oversized. Has anyone else had this problem and/or know how to fix it? It was working fine at the start, but I must have messed with something to cause this but I have no idea what I might have done. T-T

Thank you!
