Hi everyone thanks for your replies. I posted the message a few days ago when it was really bad. It has calmed down a bit now and I feel a lot more in control of my mind. I have seen the doctors about this several times over the years and I've been referred to counselling and CBT therapists. I've not found the CBT very helpful as the OCD/intrusive thoughts seem to come back stronger. I have been on Citalopram since 2010, initially for depression and now to manage OCD. I tried Sertraline last year but it made me more paranoid. Ive never tried any other medication. I was offered a meeting with the health and wellbeing advisor at an unemployment programme I am on at the moment. He has a specialism in OCD so I had a talk with him yesterday. He is going to try and get me some more information on managing my symptoms. I'm not sure whether to try any other medication.
