Well T’s are human and they have a job/practice.. they must keep appts booked, they like everyone has to pay the bills.
I personally don’t think T’s should promise to be there forever. So many things can happen. They can move to other cities or states, stop accepting some insurances, maybe start a family and stay home the first few years and they could even die.
My T had never said he will always be there for me. We have always agreed as long as we both can work together we will.
You are making a wonderful change by leaving such a toxic environment, it’s likely you won’t need twice a week , every other week might be just fine since your stress will decrease.
I use to see my T weekly for 8 years, but financial things changed , I see him twice a month and yes it was hard to adjust at first but it’s gotten better , now instead of counting down 7 days until I see him it’s 14 once it was even 5 weeks because I was out of town, then he was.
You have very valid fears and to feel very upset but getting out of that toxic office will bring happiness back into your life
