How to get motivated?!

L
I'm already 6 months pp and didn't do anything at all.. I feel ugly and fat especially when I am in public places or when my husband comes back from PT ( he is in the army) and looks so handsome.. 
How do you ladies get motivated ..?
 I wish I could get skinny over night. I was always a little bit overweight so I don't know if I am just self conscious from the beginning..
