My new job has taken me out of my comfort zone since the work is via video conferencing which involves a bit of performance. I know what you mean about the anxiety of it all putting your mental health at risk. I have had to take all my anxiety medications (I try to take less when I can) and also developed a case of scleritis (painful inflammation of the eye) which I know was induced by the stress associated with this new job. However, they say the key to overcoming phobia is exposure therapy and I am getting a bit more aclimated with being "on camera" though I still need my anxiety meds to tackle this.
Life is about trying new things. Dolly Parton says, "You'll never do a whole lot unless you're brave enough to try." This sums up what is so tragic about having debilitating anxiety and why you should seek help to get it treated if it is holding you back in life.
