Nothing every goes right for me. I'm such a loser
That's pretty harsh. Why do you think you are a loser?
I am not good at anything.
Even if you're not very talented you shouldn't put yourself down. Believe in yourself and try to improve.
I'm not half as talented as you are.
I can't believe that's true. We all have different things we're good at. When you figure out what you excel at things will start working out better for you.
