Shift.ms is better if you're logged in

I am a teacher. I have outside duty most days for around 24 kids. I share the duty with another teacher to keep ratios thankfully. Friday while on duty while bringing the kids inside. I got super dizzy smacked into the brick school and had to hold on for dear life. Teachers ran to support me as they said I looked unwell and I was trying to make light of it. I couldn't walk and all I could do was hold on as they helped lead the children inside. I am really struggling as I don't feel like Im safe doing anything anymore. Anyone else experiencing this. I have not been formally diagnosed. Waiting for a scan and help.
