I think I have some form of anxiety disorder but I don't know what kind?
It sounds like you have an underlying anxiety problem that has become overwhelming. Sometimes people develop OCD traits, but they do not have the disorder. It also could be an emerging OCD disorder. I would recommend trying to figure out what has changed lately and looking at that. If nothing is different, then you could start by taking long deep breaths. . . holding your breath and slowly letting it out several times. This will calm down you parasympathetic system, and allow you to be calm. If you cannot learn to control your anxiety and stress, then you may think about making an appointment with a professional.
see a doctor or therapist about this.
