Welcome! You can do it. I'm only a little bit short of two months in and already I'm seeing major pay offs. I'm the same as you... I drank to avoid my feelings. And that is definitely something I am now learning... how do I deal with feelings without alcohol?... but I find so far that really none of the feelings are as bad as the shame and the physical destruction I was experiencing from alcohol. I'm getting better at just letting myself be down sometimes, without trying to "fix" it... and I find I recover from those negative emotions much faster than it would take me to get drunk, sleep it off, and wade through the hangover.
I know you can do it too. Welcome!
