I think OCD is an anxiety disorder, so that follows what you say you feel. While you might not have a T to talk with right now, you can begin to work on these horrible feelings on your own.

Patterns that created or added to OCD don't work out quickly, but can be managed so they don't overwhelm you IRL. Try correcting your thoughts when you find the anxiety rising. Counter what you think with what you really know to be true.

You mention soccer and the injury... I think that might be a good place to begin when you are ready to work on things.

I do hope you will talk with your school counselor. The sooner you begin on this, the less time you will be creating bad habits about it. TC!
