I am glad you were able to leave your abusive AH. I am sorry that for the moment you have to stay with your A Dad, but it sounds safer and saner than where you were.
I suspect you have some PTSD going on right now. Just because we weren't in the war in Iraq or Afghanistan does not mean that we cannot suffer from Post Traumatic Stress Disorder.
Might I suggest that you do some 'calling' around to find a counselor or therapist that 'specializes' in addiction (because they are also great with those of us that have codependency issues with an A) and one that also has a 'sliding fee scale' form of payment.
Also, in going back to AlAnon and finding some meetings that you attend regularly you will also start to find some face to face folks that you can talk with.
Anything that helps to give you some serenity.
And, of course, please continue to come here, rant, rave, scream, cry, and even laugh, but keep letting us know how you are doing because we do care so much!
Love and hugs,
