Is the outpatient treatment at the hospital individual therapy? If it is not, and you will be doing group therapy at the hospital, that is one big difference from seeing your T individually. Do you need individual treatment? Can the hospital provide that? These are important questions. Glad you are looking into all your options. If you want group therapy, but you don't fit into the hospital program, you could probably find a group in your community. Perhaps your T could give you some leads. Then you could do individual treatment with your T and group too, but not have to go to the hospital.
