 How do I deal with uselessness?

I'm unemployed for disability reasons. However, it doesn't really excuse me working from home. The problem is, I don't know what I'm good at. It's led me to believe I am useless. I can't figure out what I'm good at because what I'm good at, I think is terrible.

The hobbies I want to get good at are music and art. But everything I've done just sucks in their own way.

(Not advertising. Just a few examples):

An example of my [art,](https://images-wixmp-ed30a86b8c4ca887773594c2.wixmp.com/f/69da411c-f5ab-4da1-bd29-4bf141b8039b/de7pnh3-412e50b7-ba1e-4ed3-a84f-4d8c2dc0787c.png?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1cm46YXBwOiIsImlzcyI6InVybjphcHA6Iiwib2JqIjpbW3sicGF0aCI6IlwvZlwvNjlkYTQxMWMtZjVhYi00ZGExLWJkMjktNGJmMTQxYjgwMzliXC9kZTdwbmgzLTQxMmU1MGI3LWJhMWUtNGVkMy1hODRmLTRkOGMyZGMwNzg3Yy5wbmcifV1dLCJhdWQiOlsidXJuOnNlcnZpY2U6ZmlsZS5kb3dubG9hZCJdfQ.y9MjVCr-vJa_u7ef29Z_bcdRiUtyCRcJtASWK4pfi9g) that I think looks good, which is rare. It often turns out crap, and part of that is because I can't nail the vibrant anime art style. But it's always a chance for it to look good, and it's similar with music, whether it's a [cover](https://youtu.be/LK0M4VNvSls) or an [original](https://youtu.be/Vdl-a_nFUrc). It has a chance to sound good.

I'm also self taught in everything and can't get education on it for obvious reasons. Different styles, Covid, anxiety, etc.

I don't understand what I'm doing wrong when it turns out bad. Which ties into the uselessness. I feel like there's nothing I can do which I can earn money for.
