Well first, I would never avoid anyone because of something as silly as blushing. Ever. If anything, I'd find it cute. I really don't think anyone's been "left behind" because of blushing. It's something we all do, some do more than others, but it's not like anyone would point and laugh at you and say "HAHA, LOOK AT THAT IDIOT, HE/SHE'S BLUSHING!"
I blush every time I have to speak in public, but people know that I do, and it's not an issue. All I can say is, take it easy and try to ignore the warm sensation in your face, as I've found it actually calms down after a few seconds/minutes if you don't FOCUS on it at the time being. :)
