YANBU and YABU - it's all context 
Having been OCD in varying degrees for as long as I can remember, even as a child, I can say that at present I am only a little bit OCD, as opposed to when it would take me over an hour or two to leave the house because I had to check everything over. And over. Again. (Oftentimes it was easier to just stay in) Or couldn't throw the rubbish out until I'd been through every piece in every bag three times. And I know that people suffer far far worse.
Like TruthSweet , I have mainly intrusive thoughts, which also ramped up when PG with DC1 (wish they'd admitted pre-natal depression existed then!) (TruthSweet, it is so "good" to 'meet' someone else who has this, albeit a bad thing).
Having an elastic band on my wrist that I can viciously twang when my brain stops believing my eyes when they tell it that yes, the bloody gas IS off and no, I didn't accidentally kill someone without realising it, or yes, that fecking door IS shut, helps a little. And so on.
The anti-depressants helped at first, as they did depression, OCD and PTSD (but which came first? Wish I knew), but I stopped them as the side-affects were worse than wanting to jump off the pier. Mostly awful thoughts. Yes, they are that bad and that intrusive that I myself would rather take my chances with suicidal thoughts. Most of my 'things', such as an irrational hatred of cold-calling, junk-mail etc stem from my obsessions and compulsions. But I know I have got off lightly!
So don't hate me if I say that currently, yes, I am a BIT OCD, as opposed to other times when I've been a lot OCD. Or if people want to use it to illustrate how shiny their towels are, let 'em. I'm too busy reading through this and every message ten times before I post it, to get upset
