Did your T come back? Have you gotten any phone calls from the local clinic?
Usually, clinics do call a day or two prior to appointments to be sure that we don't forget them.
I would assume that your T must have one or two other professional options in mind for referral, in case he can't return to work for a long period of time. Hopefully, another T at the clinic is attending workshops in order to gain better knowledge of how to work through DID.
Gentle hugs to you
