Congrats on your sober time! That's awesome!!!
I wish I had some suggestions for you on this one... I know how hard it is to be happy when you lose interest in everything that you used to enjoy. If nothing else, know that I can relate to a lot of what you are saying, although mine are not related to coming off of any kind of substance.
I know you say the anti deps didn't help... which ones did you try? How long were you on them? I don't mean to be nosy, but there are so many out there and most take at least a month to fully work, maybe you just haven't found the one that you need yet? I've been on Wellbutrin for about two weeks now and so far it's working for me, which is weird because I do have anxiety issues and Wellbutrin is not supposed to work well for people with anxiety.
Others with more knowledge and experience than I have will be along soon I'm sure... I wish I knew what else to say.
