Do I?

Do I avoid getting close to people and having friends because it scares me. Am I afraid that in the end I will be betrayed? Is my mindset that everyone is out to get me and take advantage of me? I drift toward people and when I get close to them I push them away. Are close relationships with guys something that triggers my defense mechanism. Sometimes the only time that I am comfortable is when I am alone. The only problem is that being alone pulls me down into a depression. I don't think I have any answers to my own questions or solutions to my problems. Does my trauma define me?
