Hi, and welcome!
I don't think it much matters whether you consider alcoholism a "disease" or a "condition" or any other label. It has some things in common with a disease (such as the fact that none of us sets out to become an alcoholic, yet that's what we turn out to be), so it's a useful construct for some of us.
You might want to consider finding an AA meeting. For me, walking into a room with a bunch of people who knew EXACTLY what I was feeling, and who had found a way to recover and live happy lives, was HUGE. It gave me a lot of hope, and when I left, I no longer felt alone or hopeless. There was light at the end of the tunnel.
Glad to have you here with us.
