Alcohol

I am 19 weeks and a week ago I went to a festival to check out the music and bumped into some friends and it triggered me to drink. (I am a recovering alcohol) I had 3 coolers and felt so bad about it and I know there's no excuse for what I did but I've been stressed lately and was being selfish. I'm still working on how to deal with my emotions and work through things and I had a slip. My friend found out and started harassing me all day saying thing like "you don't deserve to be a mother" "I hope your baby is taken away" "you ruined your kids life" "your fucked in the head" and plus she got her boyfriend to message me. The things she said was pretty rude but I didn't let it get to me because she has always been very judgemental and rude about everyone's life. I'm just worried now about FAS and how other people look at me. I would still love my baby if it had a disability or not but having someone talk to me like that was shocking. I could never say things like what she said and trust me she said a hell of alot more. I'm trying my best with stopping drinking and this is huge for me. I just need to know someone else out there at least drank too or give me they're thoughts of what they think of this whole situation. I need a mother's advice..
