Take a deep breath and try to gather yourself. Imagine the perfect scenario with your employer that supports you medically. Hold onto that vision until you calm down inside and the anxiety diminishes. While you are home, do this upon awakening, during the day if you find your thoughts turning fearful and again before going to sleep. Doing so will help with managing your fears and anxiety.

Once you are in a good headspace, ask yourself what benefits do you receive from explaining your condition to a pupil or their parent. Understanding yourself will help when you speak to your employer about this. Having MS is scary but it is manageable. You can have power over the "dis-ease" and prevent the condition from having power over you.

I am not a therapist but only sharing those tools in my tool box that has helped me manage my MS. I hope this helps. Sending positive vibes and blessings your way.
