i truly understand the anger. And living with the problems that have been brought about by her drinking could cause you those anxieties. I hope that you get help for them, and that you get support from others who go through this.
We were so angry at my mom, we made fun of her, just to relieve the pain that we felt. I made some peace with her, before she died, but it was never what it could have been.
i did go to aca group for a while, and it helped a lot. perhap you could join one and work the steps? there are some here, actually. It helps a lot, for you have your life ahead of you, and should be able to live it to the fullest.
is there any funding for someone with your problem? could you get someone to come and help you., from a counselling center?
how about some books on your condition? that may help you.
wishing you peace, and freedom from the anger.
i hope that your mom gets some help too. if she harms herself, or anyone, you could get them to put her into treatment for 72 hours.
take care,
chicory
