It’s hard to stay positive after you have been looking for a band for such a long time, keep looking, something will come along when you’re probably not expecting it.
I have checked out a lot of your Youtube couch videos, your playing is definitely competent and you should have no problem joining a classic rock and blues band, I recon I have played 90% of those songs in your videos over time and are still playing some of them in my current band.
Unfortunately age creeps up on all of us, I listen to some band recordings I was on from twenty years ago and I know I definitely cannot play to that level now, I have lost a certain amount of dexterity, I started off bass being a 100% pick player, over time I have transformed into a 100% fingers player, I would now struggle to hold a pick due to a medical condition that’s now with me for the rest of my life.
