If you had b-12 shots as a child you might need to restart them, go to your primary doctor get bloodwork done, you might be low again, my doctor told me I'd need b-12 for life, I take a sublingual tablet from a store called sprouts, it helps.
Worried about
you and hope your doing better soon. try getting an appointment for your primary and ask if someone you know could give you a ride.
Since you liked bowling do you have a bus service that could get you to a bowling alley? or can you ask a friend. Might be worth going and see if you can get placed on a league. It's something to consider and your probably very good.
A joke and hope you don't mind it:
Two gentlemen neighbor's were talking and the one asked the other "how did you find out your wife was cheating?
"Well, she came home from bowling and she said she had a 302 game"
