I use paroxetine for my OCD and the tools gave me by
https://mindsetdoc.wordpress.com.
What I used for my OCD and I keep using is: let the thoughts come and go. Don't suppress them, don't judge them, let the appear in your mind and walk free. I know it's hard, that the magic thinking will make you believe that if you don't attack them, you don't do the ritual to overcome them, the most horrible punishment will occur and it will be all your fault.
But that only made it worse. Nothing will happen if you let them pass. They will not invoke the wrath of god or karma. I had and still have so many fantasies and catastrophic belief (for years I imagined hurting my mother with silverware and I punished my them for such thoughts both physical and emotionally or that if I closed my eyes in the bathroom I would be transported to another reality just the same but I will leave my rotting corpse and destroy the happiness of my family, for example) and the less I fought with them, the less I judged me a monster because they appeared, the less they hurt me. Is the same activity that apoplexy advice: ERP.
Oh, it will be terribly uncomfortable at firs, the uncertainty and weight of the anxiety will feel crushing But we are used to that. And with each day it will be less, it will hurt less and you will be stronger. That I can promise.
One of my tools is, when I'm having those thoughts is to try to live in the now by: saying who I am, where I live, what I have done, what I'm doing, the day and hour I'm saying this. Without using adjectives of any kind. Just the facts. To ground me in the here and know because that's what anxiety and OCD rob you, of your present moment for the what if and could happen.
I hope this can help you. Take care.
