Slummy Mummy hoping to become YUMMY MUMMY!

Options
Hi Everyone,
I'm looking for motivation and support!!!!
I'm 23, and last weighed in at 219.8lbs, and I want to be around 140lbs,
I have 3 children, 2 year old twins and a 3 year old, all delivered by c-section so my tummy is a bit of a mess at the minute!!
I want to lose weight for many reasons; my children so I can run around and play more, and to help my fibromyalgia.
I'm currently in college hoping to start a nursing degree next year so I need to be in better shape for that too!
