"Mental Health "support" in Shetland"

I have been trying to get support to change medication for depression and anxiety from the mental health department for the past 18 months. I have had a total of 3 appointments in that time, during which time I have been prescribed an anti histamine which did nothing, and another medication which was not helpful. Neither of these medications were for depression and anxiety. On the 3rd appointment I was informed that the problems in my life were due to the fact that I, as a person, am too damaged to maintain healthy relationships and not medication change. My doctor sent another letter to the mental health team as I was experiencing increased suicidal thoughts and regular self harming. The letter stated dates that I would be off island, the appointment I received was during those dates. I called and stated that I could not attend and would like a rescheduled appointment. This was over 2 months ago and I have not received a new appointment yet.
