I think that you're talking about childhood trauma, abuse, and several addictions. It's okay - these things can certainly be managed.
I would strongly suggest that you seek a counseling therapist that specializes in trauma. Sometimes, traumatic childhoods can result in a variety of issues that are based, solely, upon the family dysfuctions. And, it's not uncommon for children exposed to graphic p 0 r n to experience serious relationship issues. "p 0 r n" does not reflect "normal" or "healthy" relationships, and a child's psyche is simply not mature enough to process the graphic visual imagery - even adults have a hard time separating the imagery from reality.
So, keep working at it and give yourself plenty of time and patience - and, TIME being the main thing. It can sometimes take years to process through childhood traumas because they are so deeply buried within our memories.
