As someone who lived through depression and abused drugs, in the same way you have been, in the past, I have an important message for you.
The drugs compound and reinforce your depression. The pit gets deeper and darker the longer you languish in it. You won’t have the tools to climb out until you put down the intoxicants.
There’s light at the end of the tunnel. It took me until my mid 30s to stop drinking and drugging myself to death. Plenty of mornings where I probably shouldn’t have woken up from the cocktail I consumed the night before. Six years of sobriety later, and I have a wonderful partner, friends that actually care about me. A career that is stable because I am stable.
I’m not going to beg you not to hurt yourself, it’s your life and you can do what you want with it. But you can choose to be better than this. it is equal parts self-determination, and relying on supportive communities that will help you. If you would like help finding a narcotics anonymous or alcoholics anonymous chapter near you, DM me and I’ll do what I can.
