Your problem is not your bad history
Everybody has something bad on their history. Some people don't let that stop them. Others do. The real problem here is not your bad history, the real problem is your inability to let it go. Did you ever learn how to let things go? Probably not. You probably learned to chew in your history, to relive it, to let it completely cloud your present day. You learned how to do that. Let me emphasize that again.. you learned how to do it. What you need to learn is how to let things go. What does that mean? Did anyone ever show you how to do that? I'll tell you one thing that does not work very well: talking and venting about your bad luck. Talking and venting help for a minute. But nothing changes. Change only happens when you learn how to let it go.
