I have not talked to my parents or friends about blushing, but I do have my own method to stop the blushing. In public, I put on a poker face, try to make myself devoid of feelings so to speak, in order to stop the blushing and the embarrassment. That's a bit extreme because some people have commented that I don't smile. I look like a robot in public.
I guess you could say I do something similar to that. I just try avoid all people and mentally convince myself I am some place else. Sometimes I feel like it goes better if I just don't care if blush. For example if a bank teller starts talking to me I know I'm blushing yet I continue the conversation as if nothings happening. I'd assume it's probably pretty awkward for the other person.
