Weight loss after babies.

Sierra
So I had my 3rd child about a year ago... ever since I have had my children my body has gotten worse and worse. I know nothing about eating right when to eat or how many calories to eat a day. Everything I try to find it online everyone wants to charge so much for a little advice. Plus I don't have the motivation...I feel fat and ugly and useless and I feel really bad for my kids cause I don't have the energy anymore to play with him...someone please give me advice on where to start or how too. I want to lose like 60 pounds...plz...it's my goal.
