Have they really driven me crazy? ?

I'm currently 29 years old. Through the first 20 years of my life I was forced to live in solitude by an emotionally abusive alcoholic uncle. I was afraid to have friends over because of his violent rages. After I turned 21 and started my career I lost myself in my work. I became a heavy workoholic working 6 days a week and constantly focusing myself on fixing other people's problems. By 29 everyone's lives had begun to settle down. I had changed careers to something completely slower than what I was used to. As the haze began to wear off I realized that I have problems with intimacy and establishing friendships so I began to see a counselor. In actuality I had still carried all of the signs of being in that abusive environment. I still seclude myself from people who want to know me as a person. My question is that if it's possible for someone to drive a kid so madly insane that they don't really know who they are? Is it possible to break a cycle that you have known all of your life to be so lost in your own thoughts that you can't even determine what is real or not? I'm not a bad person. I just don't know who I am.
