I do not and would not, accept a removal from the mental health team without wrtitten and very clear reasons why.
The rationale behind this is my view on funding streams...and why you may need to get back to the NHs in the future. More importantly, however, is the level of care that is currently needed and provided. If there should be any deterioration in health, behaviour, need for additional support or even a review of medication, you are at the back of the queue again. Don't accept this at all unless hou have good reasons given.
( PS... This advice came to me from Admiral Nurses)
