I also have severe anxiety, along with PTSD. I find that my symptoms are actually aggravated by alcohol (especially withdrawal). My new insurance kicks in on the 1st, and I have a plan to address my mental health needs with my doctor then. In the meantime, I've been going to lots and lots of AA meetings, and reading this forum religiously. Dual diagnosis can be tricky, it's always tempting the think of drinking as "medicating". But you and I both know it's not.
Hang in there. Stick around, there's a great group of supportive and kind people here.
