my moms an alcoholic.... im stugglingI

my mom is an alcoholic has been for years now. i dont live at home but my 15 year old sister and 10 year old brother do. im 21 and moved out with my own family. my moms drinking is so bad she wont go to work for a couple weeks at a time. she will lay on the couch and cry for days, not changing her clothes, neglecting her kids, not eating etc. she also has horrible symptoms of withdrawl when she stops for a day ( vomiting, shaking, insomnia, paranoia, confusion, anxiety, irregar heartbeat, etc) shes a very mean drunk as well. i used to take care of her and help and other family members and myself have tried to intervene. shes driven drunk with my siblings and more. its a bad problem. im struggling myself with the situation. im trying to help as much as i can. but i was wondering. can i go to aa meetings for support? i dont know what to do anymore. also she refuses any help and any problems. she gets overly angry at me whenever anyone tries to help.
