I'm sorry that you're having such a hard time now. I think that sometimes people can put too much faith in their therapist. Or that they can rely too much on a therapist.
I've never had one who I felt could help me get through a day or a week. Maybe I've never had a great one
You're having a really hard time at work now. Is it possible you could take some time off? It might be best for you and your future relations at your work place. Just a thought.
To answer your question...I've never had a co-worker who I'd like as a therapist.
If I could have a fantasy therapist though I'd pick Joanne Woodward
