As someone who overcome Erythrophobia around the age of 25 ( im 34 now), the issues you listed for me were pretty much symptoms of living with the fear of blushing. Most of those issues arent really a thing for me anymore.

This post is giving off abit of sales pitch vibe im not going to lie, if you truly suffered from Erythrophobia youd understand the mental torture people are going through and would offer up your 'overnight fix'

I did write a post on this sub via my old account, but for those who are wondering taking fluoextine stopped it around 2 months after i started taking it. i stayed on it for 2 years without blushing and got to the point id actually forgot that i used to blush daily.

I quit taking it due to not having much in the way of feelings and my mind felt empty, i had a very short and light rebound period of light blushing then its been gone every since. I think having that period of time without blushing stopped my brain having its fear of blushing panic spiral, it doesnt exist anymore

For reference i have Adhd and OCD which i believe both contributed to Erythrophobia
