Sometimes disorders are like side effects of other disorders.

For example, I was a bipolar kid. Because I overreacted to things, other kids thought I was a nutcase and went out of their way to avoid me. That gave me some social anxiety. I couldn't trust my own emotions or judgment, so I could never be sure if I was behaving appropriately. I seem to have the permanent sense that I'm doing something wrong and everyone knows it but me.

Of course, growing up feeling ostracized meant that my self-worth was horrible. I saw myself as this disgusting freak that everyone else hated, which led into my eating disorder and self-harm. I wanted to take control of my appearance, change myself from the disgusting freak to a normal person who deserved to be included in life.

So the path of my life was this: Uncontrollable emotions --->ostracism---->fear of my bad judgment ---->self-loathing ---->desperately wanting to be accepted ----> needing to prove my worth through extreme behavior--->frustration for not being able to succeed ---->hopelessness
