Calm down first. You feel like you have no worth in life? That’s not true. Everybody in normal society has something positive to contribute. So go for a walk, relax, and don’t stress.

Hobbies are meant to enrich your life. If we all sat at home our whole lives hoarding our money like a dragon on a pile of gold we’d be miserable.

Did you overspend? Yes. Now don’t let it go to waste by selling it before you’ve even had a chance to enjoy it. Or if this is something you don’t enjoy, sell it for the loss and maybe consider $/hour enjoyment as the “loss”

If you get $10/h of enjoyment out of it you’re doing the same as going to the movies for example.

Hobbies generally cost money, very few do them to save money or make money.
