New to this

Hi my name is Laurie and i am new to My Fitness Pal. I have a friend who has been using this app for a while and i couldn't get this app to work on my phone until today. I am hoping that my internet connection holds out lol. I don't have one of those wrist things so i am trying to keep track of things the best i can with my pone app. I am 34 and physically disabled and about 50 pounds over weight and wanting to get down to about 110. It is hard for me to get motivated when doing this by myself so i hope i can get some motivation and encouragement here.
