Sorry they turned you away.

I'm in Canada too and unless you can make a really good case for being unsafe they will turn you away. I had a really bad experience where I took myself to the emergency room and they didn't believe me and convinced me to go home. The next day I still wanted to kill myself, so I went back. This time they admitted me, but they treated me really poorly, labelled me as manipulative, and I didn't get any help. They decided I was BPD, and sent me to a therapist who only dealt with borderline clients. The therapist said I was definitely not BPD and dumped me, because she only worked with borderline clients.

After all that trouble though, since I had no help and no one was managing my meds, I ended up psychotic and the school psychiatrist sent me to a psychosis program where I am now with the best psychiatrist I've ever worked with. If I need to go to the hospital, I go through her and I never get turned away. And if I'm in crisis and don't have an appointment for a while, she alerts the mobile crisis unit in my city so that they know who I am and my diagnosis and that I'm in crisis, and if I need to go to the hospital I can call them.

I don't know if you have anything like this, but my city also has a crisis house - it's non-medical, no doctors or nurses, but it's 24 hours a day staffed with experienced counsellors and you stay for 3-5 days and work on goals. I did that last year and it was incredibly helpful.
