Detox can be the pits, absolutely. Once you're done with it though, you never, ever have to go through that again.
It's my experience that after I quit drinking, my anxiety and depression lifted. I know it's easy to believe that alcohol is relieving your symptoms, but it's usually caused(or perpetuated) by the alcohol itself.
So, quitting is something to discuss with your doc. I quit cold turkey, (not a smart idea) and felt like crawling out of my skin. I had night sweats, poor sleep, and I was utterly physically exhausted for about a week. Good news is, it's over and I can choose to never let myself go through that again.
It does get better. Keep us posted.
