Hi there,
It's been almost 2 months since my breakup, it was a really nasty one full of his anger and verbally abusive behavior. I also got some sessions with a therapist and have done some reading on codependency and al-anon, which is helpful.
The biggest challenges for me so far have been dealing with the aftermath of the breakup, the loneliness and anxiety have sometimes made me doubt my own sanity and whether or not I made a good decision. I think it will take me a while to repair my self-esteem as the things that he said to me keep richocheting around in my head like a ping pong ball.
I think the important thing is to remember that you could never control him and his drinking, I'm sure they are teaching you all about that in al-anon.
Anyway you are young and I'm sure you will do fine, keep taking care of yourself and get whatever help you need.
