trying to process PMO, PTSD, ADD, and childhood abuse/neglect

So, I really don't know where to start with all of this as I'm still processing things.

Basically, I'm a nearly 28 year old dude who's been PMOing probably an average of 2x a day since I was ~12. I've been out of college and on my own for quite a while, but recent events have caused me to start pondering my childhood events.

The short version is that my dad always cared more about accomplishments than he did about people (including me as a kid). Never a single ounce of empathy. I found porn when I was ~12 and was just a mess throughout jr high and highschool - tried to kill myself, got sent off to the mental hospital for a while, had horrible problems with ADD, etc... All dad did about it was tell me to shape up or I was headed to jail - threatened to kick me out, blah blah blah. Never actually tried to sit down and help much - just sent me to a bunch of counselors and expected them to fix it or something.

Moving on, I've just taken some quick tests for PTSD and basically scored off the charts. I'm starting to realize that my PTSD symptoms may very well be from emotional abuse/neglect as a kid (scored very solidly in those tests too). However....I'm also wondering if long-term PMO (especially during adolescence) may have helped cause it too.....? I'm sure it at least exacerbates it a good deal and I want to get rid of it. I'm also wondering if any PTSD effects are solely from abuse/neglect and PMO was more of a temporary 'out' than anything else at the time and hasn't really caused much of anything that's not reversible in a year or so...?

I don't really know... I'm still trying to process all of this junk. I guess I'm just hoping someone with similar experiences might be able to drop some knowledge and/or experience is all.
