I have tourette syndrome why sounds similar to what you described. Bringing it up with your psychiatrist is a good idea. If you can distract yourself from obsessing about trauma it might help.

I've heard that trauma can trigger OCD, so it sounds like a good thing to pursue, Pokemonkid.

OCD is in the"anxiety disorder" category. We get the symptoms initially because we have no better way to distract ourselves from whatever our anxiety is. Now MY OCD is triggered by anxieties about damn near anything that can go wrong in the lives of people I care about. Not much to do about that other than stop caring about people or get a LOT better at relaxation techniques.

If your OCD is triggered by PTSD, then once your trauma therapy gets to a certain point, your OCD will pretty much clear up, since one is causing the other..

I am diagnosed with both.
Its hell.....My OCD presents itself in intrusive thoughts the trauma related thought it torments me all day..

I also get obsessed doing anything shopping, when I was trying to start my business I would go so obsessed about it and compulsive working on it obsessively to the point of a perfectionism no one could give me..
So I would eventually burn out and leave...

Don't mean to hi jack your post just giving you samples of why I was diagnosed with OCD.
Behavior like that plus intrusive non-stop thoughts.

OCD presents itself in different ways. Some people clean, some become obsessed with thoughts, some doing something good to the point of being bad for them, some doing something destructive...

But its usually something that takes away from your life and you just can not stop.

I absolutely will NOT forgive you for not understanding well, Pokemon. That is neither a sin, nor an offense, so it would be like forgiving my grandson for his innocence. What's to forgive??? I don't understand it, either but I know for absolute certain it hurts like a father fuck. Feeling safe and blessed to ask the questions and sort the chaos gives me hope that understanding is possible. Maybe even some relief to go with that understanding?

Anyhoo. . .

I have never been dx'ed with OCD (like I need yet another dx!!!), but I obsess ALLOT. Especially when I am in episode and triggering all over the map. Repetitions, rhythms, patterns, physical movements, etc., help me to drown out the obsessive thoughts, flashbacks, et al. Counting, figuring statistics, singing the same song over and over and repeating phrases would be among my personal faves. Yea, the comfort can easily run amok and become destructive, when consciously channeled, I believe they can even be therapeutic. Kinda like meds? Conscientious use can of tremendous benefit. Abuse can be disastrous.

Don't know if it fits your case, or not. Just sharing.

Gentle support while you sort your own, unique case, Pokem. Hope you feel free to sort here, with zero need for forgiveness. Just getting by with a little help from your friends.

The only silly question is the one not asked, IMHO.

If the OCD only happens with PTSD, I'd say it's not truly OCD, but a symptom of the PTSD.

I know I only get certain things when I'm in a triggered state...

Look for patterns, my friend. You'll find answers.

Hugs.

I'm with Arfie and and Deli cause there is nothing to forgive and there are no stupid questions. We all have things we don't understand.
I'm also with Arfie on counting, sing songs over and over ect. It is a great way to get things under control.
Please don't ever be afraid to ask any one of us a question. We may not have the answer but I'm sure we can help you find it.
