is OCD and PTSD linked?

I wanted to ask if ptsd is linked with intrusive thoughts? I had a incident last year which gave me ptsd. Im trying to recover now but in the meantime I found I suffer from OCD, I had these intrusive thoughts and compulsions that left me drained for days. I feel at times as if someone else has taken over my mind and is controlling my thoughts my feelings..feelings! and when this phase (of being controlled by some invisible power passes) I feel so drained so weak and numb and I feel like an empty shell, because the thoughts, the stories the images that come in my mind leave me so scared and weak and hopeless(and all these images/stories are related to that event). its like im still living in the past, I know I'm writing this but sometimes a memory or something catapults me in that time. i cant sleep, as soon as my eyes start to droop I get terrified that maybe by sleeping or relaxing that horrifying event will.. i don't even have guts to complete the sentence. and the most strange thing..we all pray for us for our happiness right? but voices inside me are ready to pray for the very opposite i want to e.g i fear of getting hit by the car(just an example) the voice inside me will say may you get hit by the car..like its literally begging and praying this to heaven) they were so loud back days that I started to hit myself on my chest(thats was the source of voices..) then I started to threaten it with a knife to shutup or Ill stab you)theses voices are still here and I noticed that if something cause a trigger, they come back , the feeling of mind getting possessed, horrifying urges and thoughts, everything comes back.. these leave me hating myself and its like 70percent of my left part is corrupted while the rest 30% bit is safe..but my thoughts are no more my thoughts.. I feel someone is infiltrating my mind and forcing me to think I don,t want to.. someone is constantly talking inside of me what is it? please please help

please help, im going insane

Hey,

I'm sorry you're struggling so much with this atm.. I'll give a proper reply to this a bit later on - right now i'm still thinking about this a bit..

I can kind of see how OCD would worsen alongside an active PTSD episode - PTSD has a habit of making any current or latent mental health issues come to the front.. (ie, I suffered from severe social anxiety and agoraphobia in my most severe episode- i'm already prone to these)
not sure there's a link other than that but give me a bit of time to think this through a do a little bit of research and I'll give a better answer.

Thank you ever so much!

Hi, I too feel the way you do. After a certain event happened 2 months ago I haven't been the same. I guess my ptsd came back with the vengeance. At times I too feel like some other person or invisible force it controlling my mind, why would I choose to think all of those negative things? Why would I choose to remember or relive those experiences, again? I know that isn't me, it's my OCD and anxiety telling me these things, doubting everything and anything which makes it even more difficult to heal. You just have to remind yourself that this is your own mind doing this and nothing else, and ignore those thoughts. It is hard and I struggle with it everyday. Like you said, it's hard to relax, I know I often find myself distracted with something else, or suddenly relaxed and I'm not even aware that I am until the flashbacks return. I think we're afraid of the flashbacks and negative intrusive thoughts never leaving. Like you said, even writing this I still feel them there. I just want a rest from this all, and I'm sure you do too, but don't give up! It's never easy but healing is possible! Good luck to you and everyone else going through this.

I believe OCD and PTSD are often co-morbid due to the intrusive thoughts which can turn into ruminating or obsessive thoughts.

I was diagnosed with OCD linked to PTSD due to severe episodes of trauma and abuse over a prolonged period of my life and also very recently. I was prescribed Abilify on top of Effexor because my OCD was getting out of control.

You are not alone. Please know that.

I was diagnosed with chronic ptsd in 2002. I'm 48 as of Dec 2014. Most of the time I am able to keep my triggers at a safe distance (though not when I was 1st diagnosed, I had to learn coping mechanisms). However, in the moments when I get triggered despite my best efforts I find myself displaying ocd symptoms almost like a muscle reflex. I've done this for several decades. Though I have not ever been formally diagnosed ocd, lately I have been paying more attention to this symptom because I am realizing that (in my case) I can attribute much of my frustration to ocd attempts which those around me fail to respect or understand. Obviously, this is something I plan to discuss more in depth with my therapist, but I find it reassuring that others are also wondering (as I have been) if the two are linked.
