I'm new! Looking for friends and motivation! :)

Hi Everyone! I'm new to this and am hoping posting on boards and meeting friends here helps with motivation and gets me on the right track! I'm a mom of 4, busy (but who isn't??) but I HAVE to get my stuff together and lose weight. I'm 35 and starting to feel the effects of not being healthy or at an ideal weight. I'm very lucky to have a supportive husband and family, but I have trouble with staying motivated. I'll be doing great for a week or two, will start losing weight and then I'll fall off the wagon. Any tips to help me stay on track would be much appreciated. I love reading through the success stories on here and seeing how great everyone is doing with their goals. Hopefully I'll be in that category soon! :)
