New job stress!

Today I have been on a course and I still feel rubbish, usual Thursday running around, but cancelled a few lessons because of snot. Tomorrow I start work at Nursery doing some music sessions and although I am chuffed to bits about this I am feeling the pressure. I think the fact that I was told I would be "upskilling" (what does that even mean?) has stressed me out. 3 hours later I have planned and not at all ready to go!!!!!! Bed first!
