I'm frighten that one of these days I'm going to pass out because of my diabetes what should I do
Well it can happen. But remember passing out can happen to anyone at anytime. My friend is on an insuline pump and passed out while driving on the highway, no one was hurt luckily. It can happen, but don't live your life in fear. Become educated on the syptoms that happen before you pass out. That is how my friend got somewhat safe into the emergency lane when she passed out.
don't be scared. I dont know if you like th jonas brothers, but if you dont, nick jonas has diabetes and he manages it very well, he kinda has too. He talks about how he does it, all you have to do is get over your fear and learn to manage it. Passing you would be bad but not the end of the world. -sorry if sounded harsh.
