We (creatives) are our own worst critics. There have been many times that I felt the same way about opening an art thread or posting something I've made (especially elsewhere, mind you, because everyone here is so nice), because admittedly it opens you up to a world of vulnerability. I've also had a lot of brutal critique dumped on my head publicly for it (public reviews, discord servers, forums, etc), and there's even a web-zine that wrote an article about me basically poking fun at my music (which, in retrospect I think is very endearing and hilarious in a roundabout way, because at least they featured me in an article, lol).
But honestly, through the years I've realized (aside from it making me a little emotionally stronger about those particular vulnerabilities) that if I stop, I'm going to let them win. It's just not worth it for me, and I firmly believe that sharing your art (if you feel so inclined) enriches all of us. But with that said, there's no pressure to share anything you don't want to share - I just wanted to put that out there in case it helped anyone with those feelings of inadequacy that get the best of every single creator in the world.
I'd make a thread about it, but you know. "That's stupid, you should shut up" says the inner voice
