I can relate to what you have written. I can tell you a great deal about yourself, just from what you have put on the page. I too sought out many different modularuties from Re-evaluation Counseling, to Silva Mind Control, to muscle testing and reprogramming plus Rubenfeld Synergy to name a few. I found a form of meditation that allows me to turn within and heal myself which includes techniques that I can use 24/7. I've been through a great deal of growth which has included both peaks and valleys. It's a process. It does take time. You haven't indicated your age, but maturity is part of the process too.
Somewhere, you've been deeply hurt and feel you aren't good enough to have the benefits and pleasures that life offers. Learn to love yourself first (that's been a difficult lesson for me), and you will begin to let go of the self destructive behavior. Find one type of self-healing that is the most comfortable for you, and use it to find the real you. The real you is lovable and worthwhile. Keep looking, you will find what you seek.
