Beginning Again with my fitness Pal!

I've been struggling my whole life with weight issues . It is now totally out of hand. I am so Tired of not being able to breath doing simple tasks like bending over to load the washing machine, climbing stairs to tuck the kids in bed... I want to make a change, but it is so easy to eat and so easy to want and so hard to achieve and so hard to lose and keep at it..... I need a bullwhip to my motivation... need someone to push and challenge me every step of the way...
