I've had my session be interrupted due to an agitated client in crisis too.

He was shouting in the waiting room and the staff phoned in. She ignored the phone call and the knocks until the staff entered the therapy room to ask my therapist to calm him down.

We were talking about difficult things and she was gone for 20 minutes.

Midway, when the shouting died down, she sent a nurse over to me to tell me that she would be back in about 5 minutes.

She made up the time with me, and was very apologetic.

I felt I was a burden as well, like perhaps the man in crisis needed more time, but T only stablised him and rushed back to me.

I kept asking T if that man would be alright and she said he would be, and I shouldn't worry.

I feel your T should have made up your time. You're not a burden, you really aren't.
