Hi all. It seems that my long-running anxiety and depression issues might be the result of obsessive negative thinking.

Last month I tried an SSRI called sertraline and it seems to have triggered an "anxiety episode" which includes severe OCD: constant, repetitive negative thoughts that I do not seem to have when I am well, but which have damaged my confidence and caused a lot of distress.

I do not intend to act on these thoughts, the very idea of them upsets me, and I understand this is a classic sign of OCD. I also heard of a recent study in which, out of a group of people suffering from severe OCD, precisely no-one acted on their obsessive thoughts.

I'm seeing my therapist on Tuesday to start treatment for OCD. It is a relief to think that my many, many symptoms could all be boiled down to this, but I am looking for advice and tips from anyone else who has gone through this horrible experience.

Thanks in advance.
