Oh my. I am so sorry. Recommendation: seek counseling. You are NOT crazy, lunatic or anything else. You are an anxiety ridden diabetic, as we all are or have been.
You need to step up and understand that it is what it is. You can't change that. So, you can freak out or give up the fear so you can live your life--fully. Please choose your life.
You go low, you go low. You will work hard to keep this from happening, but it will happen. When I get low I alwaystry to step up, smile and go on. I can wallow in apprehension, but what is the point? Does that change anything?
You need to step out, try things, take risks. You are 18 and have been diabetic half of your life. DO NOT LET THIS DISEASE TAKE OVER YOUR LIFE. Rule it.
I have been there, but it is all about you right now, Mega. You need to stop being afraid. Honestly, I am afraid a lot, but I cannot let me be ruled by fear. Look for help, as others have suggested. Please.
And let us know how you are doing. You are in my thoughts. NOW go watch a good Friday night movie and relax...
