Hi Emerald and welcome
I am sorry toh hear about your recent attack and the strained relationship with your boss...I do believe that getting on the plane would be a challenge for anyone in that circumstance.
I am reluctant to give you advice about disclosing your issue at work because while true, you are protected against discrimination based on your illness...it can still cause a battle that you may not want to be invoved in...one that might just bring on more anxiety?
You should be aware of your rights of course, so check out this link, which outlines them well:)

I hope that this gives you some good information to keep on hand...and that things improve for you at work.
Please post with us anytime! This is a great place to come and talk with others who understand what you are feeling and going through.
