Wow, there's more of us missing digits than I knew. I thought it was just me and Frodo!
Glad you're recovering and that it wasn't worse than it is!
I lost the first joint of right thumb - amputated due to sarcoma about 5 years back.
Some Thoughts:

In my case it was really tender at first, but now doesn't bother me. After it healed up, but was still very painful, I used to tap it as hard as I could stand on the table, chair leg, whatever was handy. Doc said that would eventually desensitize nerves. He was correct. Once you get the area less sensitive, you'll learn to use it like before.
I think you'll be able to learn to do whatever you did before, maybe easier than you expect. I have a stubby right thumb (I'm right handed). At first it seemed very difficult to do things like tie shoes, button collars, but within a few months I was figuring things out.
Phantom feeling was weird at first. I used to close my eyes and "touch" my thumb tip with my index finger I swear I could feel it! Also used to itch some. That's been done for quite a while.
I would say very roughly a year until I seldom thought of it.
About the only time I feel handicapped by it now is when I'm trying to start a small screw or bolt into a threaded hole I can't see. (You know, when you're reaching down in the tiny space beside your car engine) Thumb just not long or sensitive enough now. I just have to use my left hand.
good luck MMranch!
