First, I would tell my sister if she ever lays a hand on me again..I am pressing charges..and she will be in jail..if you still have marks..it is still a possibility for you to press charges.

The part where she said you were ABOUT to abuse your father...well if that were true than it sounds like there were plenty of people there that could have "restrained" you vs. hitting you in the face!

When I was drinking heavily in 2005..my X and my children were telling me that i was doing things that I didn't think I would EVER even be capable of....If you are a blackout drinker..and with these "violent" tendencies in your family...I think it is very possible that "in a blackout" you could have been getting ready to abuse your father..

Truly, my X was telling me I was saying things like I wish I never had kids...when I was drunk...and I KNOW I would never consciously say that out loud even if it is true...because i never wanted to hurt my children...I really thought my X was brainwashing my kids to agree with him that i was saying these things when drunk so that I would quit...but I did not believe him and I did not quit.

Then one night they tape recorded me...not only did I say that I wish I never had kids..I said many other things that I thought would never come out of my mouth.

So because there was evidence of my blackouts and my behaviors I had evidence to realize that what they were telling me was true...

If you are blacking out it is very possible you are doing things you wouldn't normally do and NOT remembering these things...Even so...Even IF you were about to go after your father...#1..I'm sure your Dad can handle himself...sounds like he is bully enough to be domestic with your mother...and #2...there were enough people there for there not to have to be violence against you.
