In my experience I get over them by talking about the issue with T as long as it does not bother me anymore.

In your situation I would bring up his not replying to emails anymore and asking why he decided to do that until his explanation starts to make sense to me and I would get a feeling that he cares about me and does not do it to just get rid of me. It can take several sessions/discussions/explanations.

My assumption is that there is an underlying care and logic that somehow according to T's mind his decision serves me and is in my best interests. Because with my own T I am sure that there must be this kind underlying logic. If I wouldn't find it or if the T would refuse to discuss it or explain his decisions the I don't know if I would be able to work with him.
