Is being on a moody roller coaster normal?

okay, I'm either crying or I'll as a hornet.  I understand that my life is a little crazy...my daughter graduated high school, my husband relocated out of state in January, I've placed our house on the market and cleaned out and packed, and I had this surgery.  However, these emotions are crazy. Please tell me this is normal and I'm not going nuts.

Totally normal.  It's called hormone dumping.  Estrogen is stored in your fat cells.  When you lose weight, rapidly, the estrogen is released into your system throwing your hormones out of whack.  

It gets better when your weight levels off.

Yup. Normal.
