I've seen some neat fic for Matt having an eating disorder throughout his life and I always really like in general seeing things from a sort of developmental 'how did we get here' perspective. So - Matt's mood disorder throughout his life? I'd enjoy reading either depression or bipolar (since I think it's kind of vague in the comics?) but I just want to know what it would be like for him growing up with either of those.

Multiple fills encouraged, I am also writing a version of this already that I may or may not finish but I want a million of them regardless.
