Blushing is my hell

I'm 28 and since I was about 15 I have always blushed so easily. 
I hate it because people always comment which makes it worse.
I blush when someone talks to me, I blush if I laugh, I blush if I smile, I blush continuously throughout the day and it makes me feel crap!
I've been to the doctors about it but they just put me on medication which had severe side effects so I chose not to take them.
Does anyone else suffer??
