That's the thing, for 'Creatives' it ain't really a hobbie. Especially not a hobbie or something you 'pick'.
Like you don't just sit there and go 'hm, I think i will do music'. It's a compulsion. A need. Like breathing. You don't 'choose' to breathe, if you hold your breath you're compelled to gasp for air. You feel compelled to create, almost by some external force that emanates from the core of your being. Like a hunger.
Couple that with a proneness to perfectionism. And you have a recipe for turmoil.
You want to make, you have to make, but what you make isn't good enough (at least in your eyes). So you think you should stop, but you don't want you. It's a real inner conflict.
Your logic says you should quit, but your logic may be clouded. You being needs you to create. And you don't know what is the answer.
