Hey Mitsuki, how about you just look for another band that fits you better? You could be the band leader, writing the songs and establishing the main direction. Or how about establishing a little home studio and start a YouTube guitar channel showing off your chops, and then find people to play with? Hey, it worked for Hitori Gotō, didn't it?
Really, I have no idea what this "giving up on music" stuff is even about. It might have been true 30 years ago, but things have changed quite a bit.
