Hi and welcome
I'm a noobie too but i've spent enough time on this site to know that there are some darn good people out there who will give you all the support you need.
As well as being an alky I also suffer from depression and I agree with 51anna alcohol is a depressant BUT unfortunately it is an easy way to self medicate and numb yourself. However it just buries the problems you have and adds a whole bunch of new ones that you have to deal with, boy did I learn that the hard way LOL. I also agree that you should go to the docs and ask about medication it can be a real help. If you have been on meds before and they had no effect they might not have been the ones for you and a change might be needed, it never hurts to ask.
Take a good look around the site there's plenty of good stuff to read as well as a bucket load of inspiration and support.
Anyway I wish you all the best and good luck
Jase
