Former EMT. If you called in that you had suicidal ideation and had the means to harm yourself, it would be treated like a hostage situation, where you are both the hostage and the captor--especially if you have a weapon like a knife or gun. I can see few situations where they would send only an ambulance. The closest is if you said you simply overdosed on pills. However, at this point you need to go to the hospital. The ambulance has no ability to force you if you change your mind. Police would likely be sent along to make sure you didn't change your mind.
