I don't like the things I make myself

I'm a producer and I rap at the same time. There's a problem I haven't been able to overcome for years, always comparing myself to others and never liking what I do. I go and share my work on some sub, I want to get criticism no matter what like an idiot and when I get criticism, I say I'm not good enough and I quit, crazy right? I'm never good enough for myself. I go and listen to what another artist has done, then I listen to what I've done and say look at what that guy did and look at what I did.

The strange thing is that there are many people around me who say that my work is very good, but I can't make myself believe it. I feel like everyone says that to avoid offending me.

Maybe I opened this topic to gain different perspectives, thank you.
