Hello everyone!

My name is Rachael and I'm 17 years old. I've been overweight as long as I can remember from Elementary school and I wanna lose it the pounds!
I'm a borderline diabetic, anemic, and have PCOS.
I'm having trouble to keeping myself motivated. My family has a very low income, so that means no gym passes or exercise equipment.
We do buy healthy and junkie food. I'm very tempted to eat junk foods while they're here. But I also crave a lot of fruit/juices.
Both my parents are overweight. Sadly, my dad doesn't want to lose weight and would (honestly) rather die with a heart attack then to get lap band done or to stop eating the sweets. Although, I do thank god that he actually has no health problems (diabetic, high blood pressure, etc.) except joint problems.
My mom, she's a diabetic. She can't walk much, so it's not like me and here can walk around the block together. She wants to get lap band done.
I, myself, am thinking about getting lap band with her. It would be covered by our insurance. Me and her are both going to a seminar this Saturday.
Although, I know you need to start a plan so you'll have a routine before and after surgery, but I'm not sure how to do it, also for my mother. Since I have PCOS, it's harder to take the pounds off and I'm not sure how or what to do. I'm honestly not doing much moving around except going to places. How can I start off?
Sorry for the long introduction. Nice to meet all of you and I hope I can lose it!
