One of the 2 potential new therapists I'm seeing right now brings out that hateful feeling. I keep trying to decide if it is worth staying and trying to talk about the hateful feelings - since I don't have the ability to talk directly to people about negative feelings I am having towards them. It would give me a place to practice. Also, several people say he is really good at his job. On the other hand, I think he's an arrogant a. So why waste my time dealing with him. He's covered by insurance so there's no money involved directly from me.
If your T is good, then you should be able to talk through these hateful feelings and try to figure out where they are coming from, why they are there, and if it really is your T or something else.
