I have all the diagnoses under the sun now

I have ocd and rumination about health anxiety. Due to a traumatic incident. I have had episodes of teeth chattering recently and stumbling over my words. I know it needs investigation, it's never been serious enough for anyone to notice but there is something going on. I am in peri menopause also and other women are telling me they've had this. Anyway, I've got the internet conspiring with my ocd and flagging up horrible illnesses (that I HAVEN'T been looking up), illnesses that progress and kill within a few years. I know the treatment now is to accept that these may be the case, but I keep ruminating about it. Looking for certainty that I haven't got those. And I know I cannot research the illnesses because it will only throw up more anxieties. I don't know why I'm posting here, maybe as someone might be able to put me straight on a few things, but I know reassurance isn't the answer.
