Anger.
Sudden mood flips and flops.
Grief can cause hormone changes.
Skin changes. Break outs, rashes, dryness.
Hair loss.
Smells can trigger. Bring back memories in a flood.
Been there..done all this. Still do. Over 10 years of it.
I try to take it as a way of my big brother still teasing his little sister. I can just see him laughing that I'm 45 and getting a zit.
