I think ur doing great. I wish I got sober then at 21 I knew I should but continued and as I keep hearing and in my own evidence it just get worse. I think you are going through a grieving process about leaving your old life and can't see the future but I can assure you it gets better.
When I got sober five months ago I was a lunatic , angry n messed up I needed aa. I needed to learn how to do it because I couldn't do it alone. Theres no doubt about it , it gave me the tools that can help me go forward. I have to stick by it and my world opens. I haven't had a real bad day where I can't face the world my depression has lifted and I'm more optimistic. It takes time though for me patience is key.
Hope your well sister
Peace x
