When I used to drink because I was depressed, I used to forget why I was down in the first place. Used to chillax and be absolvant to music + things that made me happy. Until it was brought up in my head, then it made me even worse until I had to talk about it.. Of course it varies from person to person.
I escaped from that when I hit my second chance at life and realised that there's certainly more to live for than wasting my life being depressed. After all, I don't want to hit 60 years old and realise I've wasted my younger years because I was depressed over something stupid..Or really depressed at all.
I do still drink on occasions, but only because I'm catching up with friends, definently not to escape problems anymore.
Remember: Alcohol is an excuse to run away. The only way they'll be solved is if you confront them head-on.
This is just my opinion, May not necessarily be right, but yeah.
