Can you go back to what you had? I would talk to them about
it. Be honest, let them know you aren't ready for this
job promotion.
Try not to let it get you down. One day at a time. Stay in the moment, and take things as they come. Do you think this cold be a little post baby blues? It is depression and can be very serious...
Hugs, Karen
