I feel like I have no talent, please give me your advice?

Okay everybody says I am excellent at writing and poetry but lately I can't write well or do poetry well, I love singing but everybody says I suck at it and I think I do to mostly when I hear the recordings, I love soccer I am a goalkeeper and a midfielder everybody thinks I am great at that but I do not know, I really want to be great at an instrument or singing but I have tried and it doesn't work, people say my voice would be great if it wasn't so nasally and high how can I make those two things better. Please help me I am so upset.
