Loss of interest in sport?

[Ire]

I used to love playing all sports. My favourite has always been football. I played it and loved following it. Recently I've given up, I had begun to feel paranoid on the pitch. Nervous before matches until I felt like getting sick, thought anytime I went for the ball I'd get hammered, hated messing up so I gave up. I can't talk to my friends anymore, I feel uncomfortable around people, walking down the street, I don't even watch sports anymore. I'm completely at a loss to describe what has happened to me. Just that my life has begun to close in around me. I'm no longer enjoying anything. I don't know why? I want to love my sport again
