Hi Tanya,
Oooooo, BOY did you come to the right place for advice and motivation!!
And I'm guessing the simplest (and most common) advice you'll be getting is "eat less, move more," because that's something of a mantra around here.
What kind of specific advice are you looking for? You mentioned motivation...here's a good thread for that --->

Let me know what kind of advice you're looking for...maybe I can help.
And a big "Thank You" to your Dad...what an inspiration HE is to go down and help out!
Welcome! You're gonna love it here!
