Help on weight loss, for 12 year old?

Okay, so I know that there is lots of things I can do to louse weight, but theres one problem. I'm a kid, so I have almost no influence on what my parents buy at the store, and since were running low on money, we usually buy things like frozen pizza, boxed mac-and-cheese, take out, ect. We don't have the money to buy healthy foods. I love fruits, and I love vegetables, like carrots, broccoli, and probably brussel sprouts, if I ever get to eat them. I also love playing sports, like volley ball, and ice skating!
But everyone ether doesn't want to, or is to busy to play volley ball with me, and Ice skating costs money! Also, theres running, I have a oval road(?) by my house, and I could run on that, but when I tried, I felt really self conscious... I would start running, then when a car drove by, or there was a noise, I stopped.
And, before you say, "why not run with a friend?" Its not so easy to convince a friend to run with you, or even just have them over enough for the running to actually do anything! I really want to lose weight, and least 40 pounds... and at least before 2018. I just really need help, there doesn't seem to be anything I can do...

P.s, I'm.. an age below 14, and I'm 170 pounds.

I have the same problem I weigh less but used to weigh more just try and not think about it drink water eat less at a time and don't make your self sick

Ok.. I read all your problem.1st thing stop eating things like frozen pizza, boxed mac-and-cheese. Play every day with your friends at least for 1hour.Now you are a small kid, your body needs more exercise. Another thing, you can move up and down in your stair every day. Otherwise, my final suggestion is, there is a good weight loss surgeon Dr.Alper Celik at "Metabolic Surgery Clinic", Turkey.He can guide you also.He did the weight loss surgery of my uncle.
