I quit for 8 yrs when I married for the 2nd time...HUGE mistake!!!!
Kinda fell back into it by accident by helping a band who lost thier singer, then started writing & decided to start back up again, back in '90.
Since then, I've had all sortsa probs in my life, but the music kept me together somehow. I've done some tv stuff. I opened as a solo for the Marshall Tucker Band. I did a couple radio & tv commercials, locally. I recorded a demo with a band that later ripped me off & sold my songs on an album I refused to be on. Since I "quit" music, I've been in 8 bands or so, too, playing stuff from bluegrass to blues to jam band stuff to jazz to reggae & classic rock, in addition to playing my original material both on my own & in a couple bands.
Last yr I had to get that ulna nerve surgery thing...big bad horrid prob w/numb little & ring fingers on - you guessed it - my left hand! (I'm a right-handed player). Yet I'm still trying to get my hand back in shape. I still play acoustic solo gigs occasionally. I play bass in a couple bands, too.
I'm 52, and I will stop when they pry my axe from my cold dead hands...LOL!!
If you're looking for someone to say it's okay to quit, well, I'll say it; it's okay to quit. But it'll definitely be better for you if you keep with it. I've had a hell of a time keeping my chops up, but I know what happens when you quit - you lose an undefinable something that is such a big part of you that it may as well define who & what you are, no matter what you do for a regular day job, or how many kids or ex-wives you have, or how many friends you have, or whether or not you are even a "good" person. The hole is that big, man.
Either way, I wish you all the best.
