motivated?

I JUST DON'T KNOW WHY I JUST CAN'T GET MOTIVATED!!! IS THERE SOMETHING WRONG WITH ME OR DOES EVERYBODY GO THROUGH THIS? I'M FAT AND LAZY, NO GOOD MOTHER TO MY KIDS....YES, I KEEP THINKING THIS ALL THE TIME AND I DON'T KNOW WHY. I KNOW THAT I'M A GOOD MOTHER TO MY 2 KIDS, BUT IT ENTERS MY MIND AND IT GETS ME DEPRESSED RIGHT AWAY. I GET INTO THAT FUNK OF NOT WANTING TO LEAVE THE HOUSE FOR ANY REASON AT ALL. I WHAT TO EAT HEALTHY AND EXERCISE, BUT I JUST SIT ON THE COUCH AND DO NOTHING ABOUT IT.....WHY? I'M STUCK IN A VERY COMPLICATED SITUATION WITH MY EMOTICONS....THEY GO UP AND DOWN CONSTANTLY. IF THERE IS ANYONE THAT READS THIS AND CAN UNDERSTAND WHY I'M LIKE THIS, PLEASE LET ME KNOW OR IF YOUR GOING THROUGH THE SAME THING THAT I'M GOING THROUGH..I WOULD LIKE TO HEAR YOUR STORY. ANYTHING TO HELP ME GET MY MOTIVATION BACK!
