So, your current level of care and session frequency is being dramatically/suddenly changed for the therapist’s own personal convenience and benefit and not for reasons having to do with your therapy needs!??

This sounds terribly negligent to me. He/She owes it to current clients to maintain their level of care and to not take on additional responsibilities that impact their care....unless it was all done very gradually with your collaboration (regarding your own input around session frequency, other resources, long term plan, etc) and safeguards are in place to make sure you had access to extra care if you needed it while he/she was unable to provide it.

This would certainly be a deal-breaker for me. I could not trust this therapist.
