i don't know where you live, but your mom will have access to care, and potentially detox facilities. she loves you, she is just frustrated, scared and maybe a little pissed.
i too struggle with anxiety, and it had gotten really bad, it was absolutely connected to my drinking. the more i drank, the worse it got, where i couldn't even look a person in the eyes for fear & panic. drinking will not, will not improve this condition.
