Always speak up and never give up on demanding what you need and makes you feel secure, no worries , if nothing get where you ant it,change dates and get dr reschedule and also know exactly the goal for every treatment.
A journal is a good idea to keep and write after any dr appointment the main agreements you made and who will, be done , all documented for your own records, also will help you with recording improvements, side effects,changes in mood or behavior ,everything you need to discuss with your dr in the future will be a fact note in the journal.
