In the spirit of constructive criticism, I see two points here that could have been emphasized more in prepatory comments. First, the 911 call should have been made sooner ("Don't be afraid to call 911 - that's what they're there for. Just make sure you have a true, bona fide live threatening situation, then call them as soon as possible after that.").
If you are unsure you have an emergency, you probably have one, call 911. They will ask the questions to determine how bad of an emergency you have. If you are a child (under 18, realistically, under 21
), NO ONE will criticize your decision to call 911 to get other adults to you to help you out. If you are alone this is especially true. You need an adult now. Call.
