My T said she can't be my counsellor again after being my tutor as it would cause a conflict of interest. She also said I have received a large quota of the college counselling service. Also, she said she feels it would be beneficial to see a new T to gain a different perspective.

Logically I know she is right. But a part of me feels incredibly hurt, angry and pissed off.

I don't think it's fair that she could switch roles for her needs, then say we can't switch back because of this conflict of interest.
I feel that she doesn't, and didn't care at all about me.
I also feel that she thinks I'm too much of a difficult client, that's why she won't see me.
I feel like she had this whole thing planned in the first place to get rid of me as a client.
I found out at the beginning of term that she changed her work mobile number - I feel like this is my fault as I used to text her a lot as a client. Now she's changed it so I can't contact her by phone at all. I wouldn't, but that's how it makes me feel.

I feel really down and out at the moment because of T's rejection and I miss her terribly. There's no way I will see her or talk to her again and that really hurts.
