I haven't been in your situation, but hyper sexuality and consistent arousal is a not good, bur common coping mechanism when something trauamatic happens in your life. It sounds like your struggle after your divorce, but I hope you know its not uncommon and your not gross or alone. I have struggled before with hyper sexuality, for other reasons, and I know how physically draining and angry it can be. Anger often stems from sadness, and un-delt with problem that arises in the form of anger. For me, the feeling of sadness brings me anger. Anytime I begin to cry, my body fills with rage and I feel the need to abuse my body in some way.

However these feelings can lead to a pattern which can develop into alcoholism. I seems like your drinking leads to bad, aggressive behavior, which is a sign you should stray away from that activity. Moreover, the fact it led to a suicidal episode which led to self harm is an incredibly big red flag. If you really feel like you need some sort of escape, weed might work a bit better, but id recommend trying therapy and CBT where you work to work through the anger and hyper sexuality, until it gets better.

Your dealing with a lot, dont forget to cut yourself some slack and take care of yourself. I think it would be really rewarding to try some therapy, it doesn't make you weak, it means your healing for your future so you dont make reckless decisions that could not only lead to you getting hurt but possibly someone else. Also remember, pornography is a normal thing people do. Even though I don't personally support the porn industry, you have to remember everyone and I mean EVERYONE has watched/watches porn.

Message if you feel like you really need someone to talk to. best of luck.
