Time to work on me

Hi guys , I have tried this before (several times) but this time is different. I'm ready to work on me ! I have 4 small children and I have put everyone first now it's my turn. I've turned into someone I don't know. My marriage is falling apart and I need to have the confidence to walk away . I need to do this for myself regardless and would love support . I have about 60+ lbs to lose. Thanks all
