Trying to find me again!

Hi Everyone! This is my first time posting to any of the forums so I am hoping this may be the key to keeping me on track. I started gaining weight right before I got pregnant for the first time, then used pregnancy for an excuse to eat whatever I wanted. After my son was born, I just kept right on eating whatever I wanted. I have tried to lose the weight a few times, but often found out I was pregnant again soon after and would always use it as an excuse. Well now I am done having children, and done living this way. I am ready to get healthy and be a role model for my kids. I don't want them to follow my unhealthy choices, so it is time for me to lead by example. I definitely need supportive influences and a push every now and then to stay motivated because I am the queen of all kinds of excuses!!
