I'm not sure which issues you have exactly... but there is hope for us 'dysfunctional' people... Wounds inflicted by the past can heal, it's just a matter of whether you want them to heal or not...
- You have to make up your mind that you want a normal life (or close to normal anyway).
- Then educate yourself on whichever problems you have via psychiatrist/counselor, books, and any other other bits of information you can find.
- Stay with it... Don't give up, untangling such messes can and will take years, but there will be noticeable steps made.
The mind is a remarkable thing... in time, with encouragement and consistency... it can and will replace bad behavior with new behavior...
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
