Anxiety and erythrophobia is getting worse by the day

I am a 27-year-old woman and have been struggling with social anxiety and the fear of blushing since my teenage years. About three years ago, I underwent group therapy for this and started taking citalopram. The group therapy had the desired effect, and I experienced almost no anxiety anymore. I am still taking citalopram.

However, in the past few months, I’ve noticed that the social anxiety—and especially the fear of blushing—has been taking over again. It’s particularly troublesome at work, and I feel incredibly ashamed about it (which only makes it worse). I work as a psychiatric nurse, and because of my role, I feel even more embarrassed about being so anxious; after all, I’m treating people with psychological problems myself. I can rationalize that this feeling is unreasonable, but the shame remains very strong. Sometimes, all it takes is a comment from a colleague to trigger me, and I turn bright red. I am especially triggered by compliments or when I have to share something about myself (e.g., “How was your weekend?”).

I am now trying to focus on a healthy lifestyle and revisit the exercises I learned back then. However, the exercises don’t seem to be helping enough.

Do you have any tips or advice? I’ve already gone through the subreddit, so I kind of know what I can do. I just feel hopeless.
