I sometimes feel vulnerable. I have always felt well enough to look after my own affairs. Medication gave me some stability. 4 monthly or 6 monthly visits to the psychiatrist were enough. I no longer had a CPN (community psychiatrist nurse) because I was "too well". The CPN gives more personal support between visits to the doctor.
I have been struggling lately, for most of the previous year if I am honest. My only recourse was to call the crisis team and I did this earlier today. They were helpful but couldn't help directly. They would talk to my doctor who I see next week. Crisis suggests a major emergency, comparable to calling the emergency number for a physical problem. I need help to set up a support system. Some people do not have close friends or close family, at least no one they would call in an emergency. My only recourse seems to be the crisis team.
There should be a recommended course of action. Crisis suggests that you need immediate help, for example when you are a danger to yourself or others. Going through the motions until you see a doctor is sometimes not enough. I am scared that I might struggle so badly that I cannot call for help.
I am in the UK. I am sure it is different in the US and other countries.
