Hi Want,
I have mental health issues including anxiety and take medication.
There are a couple of things I can share from my own experience that might help.
I like to remember that medication is just a tool. If I stop working on myself or ask for help when I need it, then things won't change. I like therapy in conjunction with the medication. It helped me quite a bit.
Also, during my drinking, my medication was basically rendered useless. Alcohol is a depressant so it's no wonder my mind was mashed and I felt awful!
Finally, i was having panic attacks every night like clockwork, I also didn't leave the house for two months when I had a breakdown and I was very self destructive. I'm now in a position where I go out everyday, can go into new situations without panicking entirely and I sleep better. So things can change and getting sober is a great step!
