When you went to the ER and Doc did you tell them everything? How you abused pain pills, started having bad stomach pains and stopped cold turkey? I'm not a doctor, I'm not even a dude but I am an addict in recovery and back when I was using and my bf was using things didn't always work like they should have, xanax and alcohol basically shut shit down down their for my guy. I think that your definitely depressed, and with good reason to be. Depression and mental issues tend to go hand n hand. So if I were you I work first off, stop the drinking. Stop benzos. Stop going to strip clubs......the only thing you doing is making yourself more depressed by the way your body isn't responding. I would also stop taking the ED pills, since they aren't really helping you anyway. You can always take them in the future of its needed, your young, try to relax. If you have a lot going on in your brain then that could be a reason too. Also, give yourself a break. Stay away from anything that has to do with sex, maybe every thing your doing is making it worse. I would also DEFINITELY go see another doctor, someone who specializes in this area. Google it. Don't take "I don't know" for an answer. There is nothing worse then a doc saying those 3 words. It may also be helpful for you to start seeing a therapist. A lot of people shrug off the idea of talking to a professional, I used to, but I see someone. Was diagnosed with depression. And I was definitely depressed. No energy, no motivation to do anyway. Just miserable. Wanted to sleep. Now I'm on an anti depressant and feel much better.
If you haven't already, Google your symptoms. Write down everything and anything that could be going on. Take that with you to the doc. Something isn't right. Especially with the loss of feeling and discoloration. I would think blood flow is blocked, or a nerve somewhere is pinched. Getting lost in the bottle of a bottle isn't going to help you. Your just fucking up your insides. And if you aren't already craving the drink when you 1st wake up, you will be. Alcohol w/d is dangerous. If you hooked, go to medical detox.
I really hope things get better for you. Please try to stay positive.
Also, try to think back to exactly when this tingling started. Did you injure your back before this happened? Did you pull a muscle? Please see another doc
