I've been trying to get more in tune with myself to notice triggers or possible triggers. 
One issue I really struggle with is my identity and also my self hatred. Which usually people tell me, "yeah everyone can be insecure." No, this isn't insecurity. This is hatred. I can't look at my body or self in the mirror for longer than is necessary to wash my face and brush my teeth. If I do, it's just all bad. Whenever I see other girls in public or at work, it triggers my self hatred. Of why can't I look like her, my life would be easier if I looked like that, why can't my body be like that. To the point that I do not want my boyfriend to touch me because I make myself believe that he wants other girls and he hates me as much as I hate me, which is obviously frustrating for him.
I cant stand being on facebook, Instagram, twitter, and tumblr because even Body Positive posts and selfies can trigger this. I feel like I have to shield myself from looking at other women because I'll just hate myself. One day, I remember I saw a girl at work and her body was just perfect and I started getting so angry that I can't look like that and I have to be so ugly that I went into the bathroom self harmed cause I couldn't handle my hatred for myself. It's exhausting and I'm not sure how to handle it. I'm in DBT and trying to figure out how to manage BPD, but I'm just curious if anyone else deals with/has dealt with that before?
