As Much as I hate to say it, you will always find people who don't understand. In fact, you will find very few people who do. This person obviously needs to do some research on the subject. It is NOT a cry for help. It's really unfortunate that you turn to a friend for support, and that friend can't even understand, and/or accept what you're dealing with.
For what it's worth, just remember that you always have us here, and we all understand. SI is absolutely NOT a cry for attention...if it was, why would we all try so hard to hide it?
If you ever need anything, feel free to PM.
