old but a fresh start

I was on here in 2009 since then I have gotten married and had my 2nd child who is now 6 months old... I am finally at a point that I know this has to happen I am tired of not feeling good about myself and feeling that i might embarrass my husband even tho i know that is not the case he loves me for me but i want to feel like i can make him proud and i dont want my step children who are in school to be embarrassed of their "fat mama" i want them to be just be embarrassed of mom in general lol ... so I am hoping I can stay committed and reach my goal this time... wish me luck!!!
