I still read here all time to keep up with you. I have had this some too. I always wonder if it is not either meds or neuro damage. In MS (and we know the epidemeology of the two diseases is poorly understood) there is neuro damage that causes in increase in OCD to show up. I have had to deal with this. I have had times of the hideous and cliche hand washing. There is lots you can do while trying to figure out what is causing it. The bummer is, you will problaby be the only one to figure out why you are you experiencing this.
One of the major factors is stress and lets see....oh yeah you have had a ton of that lately with the death of your daddy. So be gentle with yourself and understand you may be using these odd behaviors as comfort. One way to see of these behavoirs are really compulsive is to try NOT t do them. When I did this with the hand washing....I would start so sweat and I didn't get relief until I washed. (sure sign...... ).
The usual treatments are SSRI type antidepressants.... you can google those for yourself. But also a therapist can help you figure out what you are dealing with. Lots of people can also do this on their own via journalling and self help type books. The bottom line is; most theorize that OCD is a way to self comfort when we are feeling out of control and stressed ALONG with chemical and neuro changes.
Well that is what I found out as went through this. All these ramblings are my own opinion and not at all professional! I do hope they help in some way. Feel better soon.
