~ I NEED HELP,ENCOURAGEMENT, AND GOOD DIET TIPS ~

Hi My name is Leslie. Im 270lbs but havent weighed my self for a long time. I am 5 foot 7 inches. I used to swim, regular ans syncronized, when i was younger but i kept gaining weight. I used to always walk and ride my bike and stay active but i still kept gaining weight due to the fact that i ate more calories then supposed too. Im fed up with my self and more so because i really want to start swimming again and i look TERRIBLE in a bathing suit. see how big my thighs are?! I love swimming, its my passion and i want to be on the team so badly and i need to be fit and in shape. My mom doesnt encourage me, more likediscourages me. Shes always talking about be negitively. Shes also inconsiderate. She buys fruits/vegetables that i dont like (that my siblings like) and wont buy me my requested red NOT green apples and califlower, greenbeans,etc. I really need Help to lose weight. I heard of all the health issues and i'm scared for my life. Please help.
