@Brooess – I have had severe OCD for the last 7 years or so, although thankfully i'm reasonably well at the moment. Before that it was smaller stuff like some people have mentioned. If you are genuinely worried about it, then OCD-UK are good guys and could be worth a call. If you want some info/advice from me, let me know and i can either email you or give you a call.
Your GP can refer you for an assessment if you want it, which could lead to CBT, some chemical assisstance or something similar.
Whatever you do, don't let it get out of hand as it's easier to nip in the bud before it gets too heavy. When it gets full blown it's truly awful and life consuming.
Unfortunately the main treatment is CBT exposure therapy which pretty much means ignoring those urges and living with the discomfort until they go away. It's hard work and scary and horrible. Some of the recommended self help books are really good too.
Unfortunately this life and family destroying illness is still seen as fair game for jokes and is easily dismissed, although anyone who knows a sufferer will confirm it's no laughing matter.
Best thing you can do is get out on the bike and ride as it genuinely helps in lots of ways.
Good luck and let me know if you need any help.
