Hey bro';
Don't sweat it, bands come and go. There will be another, better one.
Improve your skills if that is something you feel the need to do.
Also, open your mind. We all get stuck in ruts and develop tunnel vision.
Do what you love, love what you do ... stuff that makes you feel good, gives you satisfaction and a sense of accomplishment.
I'm 47, I've been playing in bands continuously since I was 15, in all kinds of permutations.
Honestly, I feel your pain. If I couldn't play, that would have a big negative impact on my life.
Good luck ... keep your chin up!
