My bf is a wonderful man and would never make me feel bad on purpose. He also doesn't know the extent of my mental illness because I've been able to hide it from him or downplay it. He knows I get really depressed or upset about things a bit extra, but not that I get a little suicidal over things like people being late, saying something I misinterpret, accidentally hurting myself, etc.

He suffers from his own stuff too, and recently started group therapy. He came over one night and said something like "I hope they all get better and I wish them no I'll harm, but it makes me feel better knowing I'm not as crazy as them[the others in his group]."

I asked him what that meant and he told me one member got suicidal and had to call the police on herself because she accidentally stubbed her dads toe. He said that was crazy.

I'm that fucking crazy. I spiral into suicidal spiral because I had trouble making a pizza at work. I cut myself because he's (or someone) is running late. I'm fucking ridiculous. 

I just feel like garbage and idk if I should tell him because I don't want him to suddenly see me as crazy.
