Blushing

Everyday in school my face gets completely red at least 5 times. It’s so annoying. My friends always point it out which makes it even worse. My face gets red from everything, like presenting in class, raising my hand, talking to popular kids, talking to guys, some nasty things🤢, and just randomly. It’s so annoying but I know I can’t do much. Any suggestions on how to reduce my blushing?
