New and hoping I'll finally be successful

Hi im new to myfitnesspal and Im really hoping this will motivate me. Im getting married next year. i have put on a lot of weight over the last 4 years and Im hoping to lose it all and be back to where I used to be for my wedding. I only have 8 months to do this and I keep putting it off but today is the day. May seem strange starting just before xmas but why not. I don't want to put on extra pounds at xmas so need to get focused now. Any support and help is always welcome and I'll try to support and encourage others. Good luck everyone, fingers crossed I can do this!!
