Lonely.. ranting I’m sorry

Its been a year Valentine’s Day (we broke up then) since we broke up after 3 years of dating and I seriously haven’t talked to a guy since not even as friends. I’m 21 btw. I’m over him somewhat and some part of me really wants that love back but another part of me doesn’t want to get hurt again cause that was a lot of pain. I don’t know how I’m gonna meet someone else cause I don’t go to school and everyone at my job is an older woman (I’m straight) I feel like I’m gonna be alone forever.... I struggle with severe anxietydepression and bipolar and adhd so what kind of guy would want that?? And I’m 5 3 and 200 lb so a little fat again what guy would like that... I have only 1 friend but right now she’s hurting my feelings indirectly so basically I’m just very lonely... any suggestions?
