I’m in a similar boat, but I never feel fully satisfied to release a song (probably cuz I am a hobbyist and I suck lol).
There’s never a better time to put yourself out there! I resisted it for twenty years. My most “successful” release is one of my least polished tracks. I recorded it just out of university on a Pentium with a stolen microphone, pirated software, a freebie guitar, and a ZOOM 505. It’s got 4 million listens and is responsible for half my income. By comparison, I’ve released stuff that I think sounds like it was professionally recorded in a studio that no one listens to.
