Busy Momma of 8 needing support!!!

I seem so busy all the time but with some support I feel like I could make my goal! I need some friends on here to help support me! I am a type 1 diabetic, Mother of 8 (only gave birth to 1) that works part time and really enjoys the active life! I do dog sledding and bike-joring with my husband and kids but I need to do more in terms of excercise I think. My goal is to lose 50lbs. I just got back from riding my bike up a small incline for 3 miles and it was great (once I got past the feeling that I was going to die!). Show me some love people! This Momma needs support to keep going!
