Well hello, sister!
I have OCD and anxiety (plus a couple phobias, Tourette's syndrome and ADHD).
My OCD is a little different than yours. I don't have many compulsions; only obsessions. I have obsessive, random, violent thoughts. For example, I randomly want to crash my car into trees, run people over, kill people with any sharp object I can see, kill or injure myself with random objects... I also sometimes have urges to do very... Unacceptable things.
My anxiety doesn't let me sleep. Sometimes, I worry for days. My record is three nights of no sleep. I'm terrified that someone is going to come into my house and kill me (so much so I sleep with a dagger next to my bed), kill my family, kill my dog. I'm always concerned about my horse; someone might knife her to death too. What if someone bombs my town? What if a nuclear device is set off and I'm cooking in radiation? What about that sound? Must of been a plane about to drop an explosive.
That car has followed me for three turns. Must be trying to kill me. I'm afraid to walk the streets around my house (or go to non-crowded places alone) because I don't want to get picked up my a serial killer.
Also, everyone is trying to poison me. If a drink gets out of my sight at any time, I'm not drinking it.
You know. Stuff like that.
I'm not medicated, because I have a family history of addiction (and I'm afraid the doctor is going to poison me.) I would probably abuse medication, and I can't have it in my house because of my family.
So what do I do? Suffer until I can find a better solution. Not a good option.
Time to seek help.
It feels like my brain just never shuts off... It's hard to be so nervous all the time.
But here's something amusing. (Warning: language.)
