The way it was done may not be ideal but sadly there are so few NHS resources in some area that if there are no medication issues to oversee the psychiatrist does not see a patient. If a psychiatrist prescribes medication and a patient chooses not to take it then it can be perceived as a patient not choosing to be compliant or to need the services of a psychiatrist. A dr prescribes medication, a patient chooses to not take it. Then there is not much else a dr can do and as not on medication then not under secondary care as belis86 says so not under consultant care.
Patients have choice, to take medication or not. Many people on medication are also not supervised by a psychiatrist. Same with therapy, a gp etc may suggest counselling, up to a patient to turn up. If a patient says no do not agree with it or want it then that weekly slot will not be wasted and someone else will get to use that service.
Regarding you going to crisis many areas do not allow direct access to crisis as it such a limited service. Where I live only a dr or mental health worker can refer a patient to crisis service. The psych may have had feedback about patients not using crisis services appropriately as well.
What other mental health services do you have access to? Do you want to see a psychiatrist? What benefit do they give you? I found once they diagnosed and done medication, they leave it to other gp's or nurses to monitor. Sme psychiatrists do not see people with personality disorders at all, as there is debate about whether it is even a psychiatrist illness so some areas have different teams for people with PD's.
I guess drinking is not advisable as it acts as a depressant and can react with medication,so it is good he was giving you advice, whether it was delivered in a gentle way varies. Many dr's are not how one may expect to find them. But that does not mean what they say is not helpful at times? If suicidal and low maybe the dr was saying drinking at that time is not helpful?
Why not go to your gp? Say you want a better psychiatrist, one that will give you an approach that suits you?
