Wow Deb, what a positive, wonderful post.
What struck me the most is that you are now the kind of mom to your daughter that you never had. I had a mother much like yours, so I can appreciate what a gift it would be to have a mom like you.
And no, you won't be lonely forever. If you browse around this forum a bit you'll see that everybody gets healthier, gets a life back, and goes on to meet a healthier partner. And some years later maybe even another that is healthier still. What your therapist did _not_ tell you is that squiggly line that goes up? As long as you keep working your recovery that line will _keep_ going up, and up, and up.
I left my A five years ago. I thought I'd never date again, never mind fall in love. Well I was wrong. I've had a couple of very nice relationships, now on my third one and it's doing pretty good. Life goes on. In a few months I'll be a great-grandpa and I can't wait
Keep coming back, Deb. Life really does get better, lots better.
Mike
