What to do in this situation?

i am fat. overweight and i have no life, i basically have this problem because i eat when im bored, sometimes im really bored so i eat even though im not hungry but i dont realize until later. I am the only fat person in my family .in my neighborhood ...and one of the few in my town. i have a few freinds but some of them don't even text me anymore. thats why i cancelled my cell phone service because i rarely text or talk. i talk to my freinds at school but thats it. and im not good at sports so i cant join sports, they are competetive. so they will not take a fat because they dont have good "spotsmanship". my town is dangerous and we always hear of random people being shot in drive by's so my parents dont let out of the house. we basically have no backyard because the rentman rents the backyard separate to other people who use it as a storage yard. i cant find any ways to do any effective excersise and i wish i could get out of the house so i wouldnt eat when im bored. butthats not the safest thing to do, even in broad daylight when all the drug transactions are hapening. also i feel like im separating from my freins ,back when i used to be more social and ofcourse skinny.. i always got invited to the movies and to birthday parties and now nobody even bothers calling me. nobody responds to me on facebook except for this one guy who im sure only talks to me because hes stoned almost everyday and when hes not stoned he's either sleeping or working. since i dont go out of the house much i tend to be really weird when i interact with my freinds. and theres a guy who is a totoal sociopath who just always bringss me down, whenever i talk to him in his faces he either ignores me or waits 10 seconds and says "ohh were you talking to me" and he embarreses me and takes complete control over me and i cant do anything about it because the whole football team and basically alll the popular people have his back. im pretty sure he dosent like me because im fat. so how do i lose weight when i am literally trapped in this situation?
