I think it would be wise for ALL clients to ask their T to sign a contract saying that if they need to end suddenly - they will at least do two sessions for every six months you have worked with them. So if you worked with them for three years, you get 12 sessions to process the ending. that is reasonable. Apart from being in a coma or dead, there isn't really any excuse for a therapist to abruptly bail out. It is unprofessional. It is damaging to the client. It is too easy for therapists to just walk away suddenly. If you try to chase them up about it, they can report you for harassment. No other profession can just refuse to answer your questions like this. It is terrible. So write out that contract. It may not be legally binding but it will be something to wave if the worst happens. I had the most loving committed caring therapist on the planet. A man who is working five days a week as I write this. He didn't even have the decency to tell me himself. He took a month to write me a letter which explained nothing and told me not to contact him ( I am not allowed to reply?!?!?) and he was pressured into writing that letter. I often think Aliens abducted my T and replaced him with this idiot. it is the only thing that makes sense.
