With the transfer of your records, there is a documented diagnoses. That you are stable with the treatment you have been receiving, doesn't make this go away. Continuing treatment is important to stay stable and they know this. If for some reason you get the impression they don't, your first session will remind them. The transition can be trying so take extra special care of yourself right now. It will be ok, really. Filling out the forms is a formality and so much fun (LOL). Best wishes with your new provider and hang in there in the meantime.
