I never really thought that I could have ocd. All you hear about from ocd is things like making sure everything's in order, or washing your hands a lot, neither of which I do. But...
I do get intrusive thoughts. A lot. I never thought of them as intrusive thoughts until now, but now I know. I get intrusive thoughts a lot, mostly about crime and murder. I've forever had thoughts of people breaking into the house while I'm asleep. I have thoughts of faces appearing at windows, I have thoughts of seeing ghosts or apparitions. I never thought of these as intrusive thoughts until now. But now I know they are. And they have an effect on my life. Mostly they effect my sleep, cause most of these thoughts tend to come out at night, or second most commonly when I'm alone.
I don't have many compulsive behaviours though, other than maybe sticking to strict routines or ways of doing things. If I mess these things up it makes me uncomfortable, but especially when it comes to sleeping, if I mess up my routine, I know I'm gonna have a bad night.

I don't wash my hands repeatedly, but I use a lot of soap when I do, especially after touching raw meats. I can't stand cooking with meat when it's raw. I always wash my hands thoroughly after that.

I don't compulsively check door locks, but I pretty much always have that feeling of "I'm forgetting something" whenever I leave the house. Have had for ages. On many days I stood outside the door for a few seconds before I closed it thinking "do I definitely have everything?" Then I had to remind myself that as long as I have my phone and my lanyard, I can survive.

Now these intrusive thoughts aren't necessarily a recent thing. I have vivid memories of when I was about 10-11 and I would always get that feeling of someone watching you or standing behind you whenever I brushed my teeth in the evening. Weird I know. I would always be afraid that I'd look away for a second to spit in the sick or something and when I look up I'd see someone or something standing behind me. It got to a point where I would brush my teeth standing on the other side of the bathroom with my back against the wall. It went even further when one night I couldn't take it anymore and asked for my mum to come and stand with my while I brushed my teeth. It was ridiculous.

I just took an online quiz and it said I had a pretty high chance of ocd. So yeah, basically now I'm questioning my whole life.
