Yeah, i get you. I love my girlfriend to death, don't get me wrong. But yeah, I get suspicious alot. But I really blame my past relastionships. I was emotionally abused and cheated on by one girl. she cheated on me with my two best friends. Plus my Anxiety runs in my dads side of the family and I have bad anxiety. Whenever we are going to go to a movie or like even just out to eat, I always get ready last minute (I have ADD so i suck at doing things on time xD) but i'll be rushing to get ready and look nice, and then she will already be at my house. i'll get really irritable because she will look all nice and dolled up and i'll look like crap or my hair isnt done drying or something. She'll be blasting it'll irritate me a little. sometimes I feel super confident and hyperactive and good looking, especially if she is feeling down. but if she is all hyper and stuff, or even when she isnt hyper, i'll feel lazy, self cautious, ugly, paranoid and irritable. sorry.,i'm just naming my symptoms because you're Bipolar and i'm wondering if you ever get like that
