New to MFP

I started mfp almost 2 weeks ago and counting calories has been easier than I thought it would be. I am almost 30 years old (and dreading it). I want to be in better shape and eat healthier. I lack motivation at times and it would be great to have encouragement along my journey to loose 40lbs. I am currently the heaviest I have been in my life. I have 2 great children (7 & 10) that aren't excited about the food changes in the house lately but want to help me reach my goal. I look forward to the new me!
