Alcohol Problem

I am a college student and work as a resident assistant (RA). These last two years, I have been going through a lot of emotional and physical problems. I am diagnosed with MS and a thyroid disorder, and also have severe depression and suicidal tendencies. I am trying my best to just get through it all. I love my family and friends, and want to keep going. I find that I am turning to alcohol to fix my problems. Every excuse to drink this year, I took it and drank too much. I have began to drink during the day and even go to staff meetings/RA duty tipsy. I have become a master at hiding it from friends, family and my staff. I don’t know what to do. I mentioned maybe group therapy or help to my mom and she said “So you’re a fucking alcoholic now? You want to go to AA like one of those?” And haven’t mentioned it again. I am turning 21 in July, and am afraid it will get worse if I can buy for myself. I woke up after a night of drinking with cuts on my wrist and am afraid nothing will get better. I know I use alcohol to fix my problems with men, exes, friends and family drama. It makes me relaxed and able to get through. My mom has never been unsupportive and I don’t know why she is reacting now. My father was apparently an alcoholic when he raised my older sisters, rampant drug abuse runs on my mom’s side. I want help. I don’t know where to go or what to say. I am trained as an RA to help those coming to me with these problems and can’t help myself. I’m not a diagnosed with alcoholism (but I haven’t been seen for any issues related to drinking), and I don’t think I drink enough to be deemed one. My relation to drinking alcohol is unhealthy. I don’t know what to do anymore.
