I don't think i have SP as severe as some of the people using this site, but i have enough to make me worry about it, especially when i am dealing with people i percieve to be 'above' me or have some kind of authority over me.
i told my best friend i went to counselling because i started blushing and feeling anxious around particular people and she just laughed at me. She wasn't being malicious or anything, that's just her nature. i don't think she understood what i was saying because i have never acted weird around her.
My boyfriend didn't take it seriously at first, and said i was just going through a phase and that i would grow out of it when i gain more experience in dealing professionally with people. But he's seen how upset i get when i have a major blushing episode, so now he's quite supportive and accepting in having a tomato-face for a partner. However he doesn't really like the fact that i go see a counsellor. I think that's just a little bit of insecurity on his part, though he needn't worry.
I've also told one of my friends at uni, and she's really supportive. We're both training to be psychs so we kinda 'debrief' each other's problems and she calms me down when i get upset over it, and i calm her down when she gets uptight over something. Also she even thinks she's got a touch of it herself, so we can have a laugh about how antisocial we are. I think its good (for me personally) to try and put a positive spin on it, although i'm by no means downplaying the severity of this infliction. My blushing really makes me feel miserable a times. But for the most part i'll try to get on with my life and be positive and I'll walk into her office every-other day and declare the new blushing 'cure' that i'm gonna try out to beat this thing.
