Oh, you must be so tired and frightened. It's a horrible disease.
Your thoughts are TYPICAL of OCD. OCD has about five types of awful thoughts - religious ones, the harming ones, the dirt ones and I've forgotten the other two. It's AWFUL isn't it - but you aren't going to hurt anyone.
To set the record straight in your poor knackered state:
No OCD sufferer ever killed anyone. (trust me, I've asked top docs about this. I had a burst of violent ones. You are not going to harm or kill anyone).
OCD sufferers don't go psychotic either, as it happens. (ditto).
It's rubbish to say OCD is part of your personality - it's a disease, poss genetic hiccough - not directly hereditary tho'. Everyone gets random thoughts by the way - most people just ignore them. That's what therapists mean by embracing them - really they mean you just learn to ignore them rather than doing so automatically.
But when you get stuff like that you feel quite sick with horror and of course you can't ignore them, immediately. Then, when the thoughts just come shooting in like shrieking shoppers on day 1 of Harrods sale, you think you're going nuts. You aren't. It's just an invisible, pointless, meaningless thought.
What worked for me: after ages of drug resistance from fear of going barmy, I hoovered Seroxat. Massive improvement in three weeks (showing disease is chemical).
Docs and psychs may also give you sedatives & tranquillisers - don't get the fear about this, even tho some of them are labelled anti-psychotic - anti-psychs. are used for loads of things eg epilepsy and depression, fits, even back pain, they don't mean you are psychotic. You aren't mad.
When mine started I actually thought of ringing the police and turning myself in, cackle. I've had the thing where the doc say are you a danger to anyone etc etc and then look doubtful. I was very indignant even in a broken state and the doc, who looked about 12, apologised. A lot of GPs don't know that the thoughts are a symptom of the disease, which is not helpful because OCD is v common.
I stuck to Seroxat. OCD does actually get better - I don't blame you if you don't believe me, but in the end you will be free of the thoughts.
