Hopefully there is a Mental Health center in your community? Helps to meet other people. I used to go weekly.
If not in person, then there are probably still Zoom groups one can attend. (Check DBSA.) During pandemic a lot of in person groups changed to Zoom groups, and some of the Zoom groups are still going.
I've had years where I was really bad off, and mind wasn't functioning very well. I couldn't even drive it was so bad. Freeways everything was happening too fast. Found the right medication that worked for me, recovered (took a year), now I'm fine, working high tech job, driving, etc. Amazing how much th brain can change. I'm still the same person and yet totally different from how I was years ago.
How to defeat it? Keep going to doctor. Doctor takes care of medical side, therapeutic groups and counselor takes care of mental side (helps get me through the dark times while I'm waiting for doctor to find med that will cure me.)
Blessings.
