In my relationships (speaking almost myself having the disorder) it be chaos trying to keep hold of control. When my significant other left me it be like losing a key part of my identity and it lately couldn't be. The image I enjoy of myself is what I want it to look like contained by another person's mind. I never realize what they really think of me, or eventually reckon of me. It's hard to really see myself. For me, it adjectives started when something happened to me during childhood and I granted to hide it from my parents.
