Jeremy is quite right.
It sounds more along the lines of chronic anxiety, like Generalized Anxiety Disorder (GAD) or something similar, which commonly involves excessive worries about health and finances, but thats just a stab. Diagnostic criteria for OCD is quite specific, and is based on a doctor's observation of your behaviour. Its always best to speak to your doctor if you are concerned. Hey, you may sound freaky to yourself but not to anyone else.

Its great you are going to see a therapist, maybe you'll get to the bottom of this.
