Dunkel, I agree with the others on dropping all substances to help with your mental issues. My mom and my sister had pretty extreme mental issues and I have seen that adding substances will negate any work a therapist or psychiatrist does.
I know you say you're only drinking when going out, but there was the mixing of benzos, coke and booze. I had done that in my drinking days a handful of times and it took me weeks to feel normal again. Try abstaining and if this therapist is leaving, work with her until you get your new one?
