The Blushing Phobia - Erythrophobia

Teach yourself to relax and breathe correctly when you know that you're going to be in a situation that could trigger off blushing. When you're in control of your feelings you will not think about blushing, and if you do blush a little, remember that most people don't even notice or even care about it. Remember all the skills you learned from early childhood, some things seemed like you would never be able to master them, but you did in the end because you were persistent.
Training yourself not to be so shy will also take persistence, but you will be well rewarded by feeling the exhilaration of being able to face strangers with self confidence, knowing that you no longer fear blushing in public.
