I'm sorry that your T has said that to you and I agree with HH that a new T might not be a bad idea if you don't feel heard and validated...

Once I was telling my exT how bad day I had that I couldn't have got out the bed, I spent the whole day in pajamas watching movies and tv series for the whole day, no food nor drinks etc. and he only commented "it seems like you had a very relaxing day"... I hated him for it and now I have a new, cool T who would never say anything like that

I also believe in "pure O" (i.e. intrusive thought without physical actions); however, I agree that probably it is not an official diagnosis according to DSM...
