"Lack of contact from new case manager"

I have had an excellent and therapeutic relationship with a previous case manager (mental health nurse) for a couple of years but unfortunately, they have sidestepped into another position within the health service. This required the engagement of a new case manager recently. In this time, I have only spoken to them once over the phone. They have called me 3 times and left me one SMS text. I have called them 4 times, with 2 of these calls requesting an urgent call back for one occasion of extreme distress and another to ask for urgent assistance with a medication issue. At no time did I receive a return call for either of these occasions. 

I recently received a call to touch base and see how I was doing. I have been struggling a lot with the required isolation due to the coronavirus pandemic and the removal of all my activities and programs that helped me sustain a meaningful existence and gave me a purpose and instilled some hope for returning to a more stable life and recovery from the mental illnesses, that I have been dealing with for the last 5 years. I also have had to deal with a young pet who was very unwell and had to make a difficult decision to euthanise him.

So essentially, I believe I have had limited support in the last 6 weeks, despite reaching out for support, which I have never found easy at any time to do. I have felt abandoned, invisible and forgotten. When I asked what I expected from the Community Treatment Team (in the most recent phone call I received) I said a phone call at least once a week would have been appreciated as well as a timely response to my urgent requests. I have been offered the option of a new case manager, however, I have refused this, as I feel this experience has left me so disappointed and I don't trust another health professional will treat me right or as expected.

I feel my only option is to be discharged from the service. This also means I lose my psychiatrist at the same time.
