I feel like I'm the damaged loner from the wrong side of the tracks.
How have you been so damaged from being a loner from the wrong side of the tracks?
I've been deathly sick and injured due to this. I've been bullied all my life.
Bullies have no right to do the things they do to you, but never let them make you think less of you. Change the things you don't like about yourself, get some help with it. You won't be able to get any revenge by being successful if you just wallow in self pity.
I can't be happy and successful. I will never be able to successfully get over all the bullies that have hurt me.
When you're bullied, it's easy to internalize the perception that you're weak. However, you shouldn't let the bully's opinion of you inform your opinion of yourself. If you don't feel like you can get rid of this negative self image, consider talking to a mental health professional.
