Really self-conscious about my blushing. What should I do?

I (22f) feel so self-conscious about my blushing. And by blushing, I don't mean a slight flush on the cheeks, more like bright red all over my face. And it's not once or twice in a while, but really quite often. I am quite introverted and shy, so I don't really like too much attention on me. But then what happens is that I blush bright red even when I have even the slightest feelings for someone. Let's say I like a guy at my university, then I would probably blush bright red in front of him. But that's also kind of okay. The worst is when I blush in front of everyone. I really do not want to broadcast what I feel so much, but then I can't help but do it. So, what should I do? How do I get over it?
