I'm so confused as to what I'm good at
Why do you think you are confused over things you do well?
I normally regret the choices I make.
It is normal to fail at things when you try them. It might take time or practice until you find what you are really good at.
I want to find something that I'm better at than anyone else.
That makes sense and that is a normal thought. There are many people that are not ever extraordinary at something and they still have good lives.
