im new. need some motivation!!!!

Hi I'm Kelly. I have tried this before but I never keep it up. I would love some friends so I can keep motivated!!! I can't do this alone. I'm looking to lose 10-15 pounds or more would be really nice. I'm a single mom of two busy 3 and 5 year old. I work full time and have very little time for the gym. That will change in September when both my kids will be in school full time. I need to get my eating habits in check. Any tips or help would be greatly appreciated :). Thank you for reading!!!
