SE,
Please stop drinking. Use whatever program that you find helps -- AA or a secular one. Booze is a depressant and adds to mental health issues if you have one.
Then, be sure to take care of yourself physically, emotionally, mentally and spiritually. These are components of the self. Whether you have an endogeneous mental health issue or not, I cannot tell you. But, if you do or not, taking care of the whole self will help your mental health.
Eat well; exercise; get plenty of rest. Treat yourself well; kindly; you deserve it - you are a child of G*D. Learn new things, no matter what it is. From rocket science to basket weaving - keep your mind active. And connect with your Higher Power. Take classes at your local church, mosque or synogogue, whatever.
You may find that this is a big order right now. So, start with just one of them, and build your way up to all four. You'll be surprised how well you'll feel as you begin to care for your total self. And remember, you deserve to feel good! It's how we are supposed to feel!
I look forward to hearing more from you. My puter is about to die, so, I've got to go. It's having a temper tantrum. Something wrong. I just got a new battery pack; guess that's not the problem.
Shalom!
