HELP.....What do I do?!? How do I not let it bug me and protect ppl at the same time! It is my responsibility?

you just have to remind yourself that you can't change him but you still love him. Your siblings will have to do that to. You could call aa and ask for some tips on dealing with a parent who is a drunk. It's called alateen. I went there for a while because of my dad too. It helps when other people are around and also go thru the same things....eachother's springboard and comforter.
