I won't say that you're a "bad" person, you just made bad decisions. Drinking that much can't be a good thing, perhaps you could get therapy or means like that? Maybe just spend a day alone to get away from it all. So....no, you're not a bad person, really.

You're not a bad person, everyone makes stupid mistakes. Just sit down for a moment and think about it.

You aren't a bad person, you've just made some bad choices. I recommend getting out of using drugs and alcohol right now, before you ruin your life with them. That stuff can kill you. Please don't destroy yourself. 

If someone wants to argue and fight with you, just ignore them. Don't waste your time with them. Instead, find new, true friends who care about you, and love you for who you are as a person.

About the girl, you should just tell her that you're not interested in her anymore, so that the situation will have closure.

See I have found new friends but the people I am fight with are my family. I can't really find new family. The don't know anything about my "habits" but still look down upon me. I can tell I'm the least liked out of the family and I am ok with that but Everyone is hard on me still.
