Meltdown and headaches

I had a bit of a meltdown today. The incident that tipped me over the edge was actually something others may not have even given much thought to, but to me it was huge. I had not long finished work for the day so the mental adjustment  may have contributed to my overloaded, overwhelming feelings. Anyway, since I calmed down, I have had a severe headache and have had to fight the overwhelming urge to sleep. I wish I could cope better.
