That’s not right at all! You have a right to your privacy and if any other employees know about what you discussed with your supervisor that is a Hippa issue and you should act by contacting HR. I hope you feel better soon just know you did what u felt needed to be done. You are strong. You can, you will and you must!
I know how you feel I am also 4 days out and the depression tries to take over. I smile in pain because I know in the end I will be ok. You can do it! You have done it! Now you must push past this stage and trust me it’s not easy but you have show how strong you are with the life decision you made. I applaud everyone who has started on this journey.
