I'm suffering from low confidence

I'm suffering from low confidence in a numerous amount of ways. My confidence level is affecting how I run in Cross Country/track, my schoolwork, and my social skills. I didn't have this problem last year. I was fine. I would go out there and would say to myself, "I'm going to run so fast today," But now, Every time I try to think positive, I think negative instead. I'm always thinking lately, what if I fail? I'm scared of failing. It's making me so nervous to the point where I cannot succeed. I don't know what to do.

It's like everything I do, even the slightest thing like writing a response to a question or something, I'm like "what if I did it wrong" I even used to be a good writer, but I'm not anymore because I've lost confidence. Every time I try to write, I can't find the words. It's also harder for me to talk to people and make new friends. Lately, I've been forcing myself to say hi to people whom I know, it's like my head is telling me just say hi.. get to know some people. But I'm scared of that. What do I do?????
