I've been living alone for most of my life:
3 yrs ago I fell in the bathroom- hit my head on the floor and passed out. I woke up with a broken ankle. Eventually I hopped to the computer chair (on wheels)- called 911. Rolled myself to the door and unlocked it. They came in about 5 mins- they put me in a stretcher and carried me down the stairs to the ambulance.
You need to get it done, you'll do it. It was either that or die in my apartment.
