Worst work meeting ever

I am totally devastated. I had a meeting planned today with my head teacher about how they could make reasonable adjustments for me at work. When I turned up it was the head and the deputy. I felt totally ganged up upon and it was as if they had planned before hand not to offer any help. They basically said that I am one of sixty staff all with their own needs and I am paid to be a teacher so I just need to get on with it. 

The head kept grilling me with questions even when I had gone silent and started to cry. 

I came out, drove home and had a complete meltdown. I eel awful and as if I am a great big inconvenience to the school. 

It was just the worst.
