I can relate to this so much. I felt the same way during most of my teen and early adult years. I basically felt like nobody understood me and I felt worthless. Up until about 4 years ago, I was the nerdy kid who was always picked on for being different. I hated society because I assumed that everybody was like my bullies and abusers and I got into dark poetry, Gothic art, and macabre stories because I found them easy to identify with.
Still to this day, I have severe trust issues and I go to great lengths to keep most people at a distance. In short, if you aren't like me, I find it extremely difficult to trust you and I assume that you have a hidden motive for wanting to help me.
You're not alone in this way of thinking.
