I'm sorry you're still struggling Sam.
I felt like booze was the only thing I had in my life too - but drinking was killing me, so I had to stop.
It took a lot of work for me to deal with my depression and anxiety but I'm glad I did. I've never been in a better place in a mental health sense.
Stopping drinking helped - it was hard to get a consistent measure of mental health when I was routinely poisoning myself with booze....
but I also I had professional help - I understand you don;t feel that way is for you but I encourage you to follow up on the things Anna mentioned on the other thread.
I hope you'll continue to keep posting here too - connection with others is really important
