i tend to worry a lot

Could it be that you have OCD? Worrying about small things and having the compulsion to check on everything is a sign. Sometimes the lack of control on things gets people to panic and act as you described. Rocking back and forth relieves tension because of the repetitive movement. This is usually what people with autism. I'm not saying you're autistic but that that specific movement is common among them. Also, you can't be autistic (not in its true sense) because you still have a sense of social ties - they don't. I think a meeting with a professional would do you good. If your parents are worried about you and you want to know for yourself what's going on then what about setting up a meeting with a psychologist? That doesn't necessarily mean you're messed up on the brains - but it would be healthy to know yourself more :) I hope you figure it all out soon!
