My way to better health

hello, I'm a 17 year old girl who really needs to go to a weight loss camp. I've been struggling so hard to lose weight on my own and I just can't do it. I have no motivation at home, so I need to be at a place where I can get that motivation. I'm so sick of being so big it's just ridiculous. I want to look nice for once and not think "oh I wish I looked like her" please help! I really need this. I'm just so fed up with being obese and my asthma makes it harder please just help I'm desperate.
