I had the same feelings years ago, all you can do is to let yourself to try somethings new until you find something you really love and something you're talented at and you just try for it
surround yourself with people with the same interests and people who believe in you, failure is just a new beginning and a new chance for others doors you open
Don't let those negative thoughts let you down and use it against failure
And in case you didn't find something you're good at, you just don't have to, living happily with yourself and enjoying life is the real purpose
I needed to say those words for me too, so thank you <3
