Just to also add that just because you may not be "all better" in 2-3 months doesn't mean you won't be "better off" than you are now. It may make a real difference - and you may be better able to function or, temporary in a more difficult place (this happens too) that will make things better. I'm on my second go at therapy, and while my first 3 months didn't make everything better, it did help and I did get a few months of functioning well out of it.
