Hi Aurora! How stressful for you, I am so sorry. I have OCD tendencies myself. I say tendencies because I have gotten them in check enough that they don't completely rule my life any longer. How? Oh, that's hard. I know that CBT (Cognitive Behavior Therapy) and exposure therapy helps. I didn't enlist the help of a professional in this way, but if that's possible in your situation that is the best route. Particularly since your son has epilepsy in addition to the OCD. What I did and have always done is read a lot. I understood the concepts of CBT and exposure therpy from extensive reading and just kind of did it myself. I would ask myself, "what is the worst thing that will happen if I don't do X right now." and I would force myself to forego the ritual. Over time it became easier. The self administered "treatment" caused me a lot of anxiety though. The need to perform these rituals is so overwhelming it can't be explained to someone who doesn't suffer from them. I still have OCD when it comes to cleaning, but I CAN leave the house if I don't do X and that never used to be the case. Try some of the following links for help with OCD. I feel so much for you and your son and pray you find relief.
