Take a leave of absence today

I didn't sleep well last night, I fell into a pillow, it hurt for a day, it hurt to lie down, I sat in front of the computer, it was even worse, I felt that my head was not my own, I wanted to see if it would be better at night, but it turned out that now, I didn't see any improvement, it seems that the rush is not done, sorry, I can only ask for leave today
