Never good enough

I’ve been doing really good lately under the circumstance (I’m in outpatient intensive care for mental issues caused by trauma) Until i saw my bfs snap story and he was at his parents house drinking with this girl. They are friends but i know she has tried to have sex with him before so seeing her at his house really just sent me into a rage and now depression. More like in the sense that i feel like I’m never good enough... i know its just insecurity but with having the past i have with men, abuse, assault, etc. i feel like i will never be good enough for anyone, or that i will constantly have these problems and therefore never be stable enough to have a good relationship.
