There are some issue's here hopefully you should address with your psychologist starting with your low self esteem. Everyone deserves to have a chance without being riddled with guilt over their past. You have to decide whether you can trust your psychologist enough to tell him the truth. If you are sure you can see him long enough on a regular basis then you will have time to work through current and past issue's. What I know you don't want to happen is let your past interfere with future relationships. I certainly don't want to steer you in the wrong direction. When ever I got serious about getting help and told my T about things I'd been hiding for years they were very understanding. I never hurt anyone else but I did a lot of damage to myself emotionally and mentally cause I couldn't stop beating myself up and that is not what you need to be doing. Best of Luck..
