You've got to help yourself before you go adding on an entire person to care about. I'm not going to be the one to make fun of someone's weight but if you weigh that much at 14 you really need to loose some pounds first. You don't want to end up in the hospital because of heart issues due to your weight. You won't be able to have a gf if you die from a heart attack. And remember you can start out easily with exercise. Lift some light weights at home, walk around for 20-30 minutes. Eventually you'll get stronger and loose the weight that's actually problematic.
