OCD involves thoughts (obsessions) and behaviors (compulsions). The basis for it is that obsessive thoughts cause a lot of discomfort and you keep worrying about them, until you come up with some kind of action that gives you some relief from those thoughts (even if it is only temporary). Thinking is a significant part of OCD.

Most people who have an anxiety disorder tend to have two of them or more, so it isn't surprising that you also have panic attacks. A couple of things that I have heard helped some people who have panic attacks are (1) just knowing that nobody has died from a panic attack, as scary as it is while you are in the middle of it, and (2) just go ahead and let yourself do what you are afraid will happen. If you think you are going to pass out, go ahead and try to pass out. If you try to, you almost certainly won't be able to, and the panic attack will lose it's grip on you. It would be best if you could practice this in a safe place with someone you trust, like a therapist, the first time so that you can find that it works and you will be okay.
