I'm 14 and I want to lose weight): </3

I'm 14 years old and i weigh around 205lbs.. I'm 5'8". I feel fat everyday of my life. I used to be such a skinny kid, but once my grandpa died (whom I was very close to) i started eating excessively. I gained alot of weight, and day by day my dad started hated me. He has always been one of those guys that is super healthy, and he's really fit. He goes to the gym everyday. My dad is always at work, and when he gets back the first thing he would ask me is if I went to the gym. If I didn't he would get sooooo mad, it's not even funny. We live in front of a school yard so theres a gravel field that he makes me run around 10 times, if I stop I have to do another lap. I know he 'loves' me and hes only doing this stuff for me. But honestly he could sometimes show some love towards me, he doesnt realize that I do work around the house and I have gym class at high school which they make you run alot, i have it everyday, but I still have to go to the gym everydayy. My brother used to be very fat kust like me , but he lost a remarkable amount of weight. My mom is very fat aswell. But when she was younger she was one Of the people that you think will never gain any weight. I try my hardest to lose weight, but since my brother has lost the amount of weight that he needs to, my mOm buys a lot of junk food in the house, and I say I'm not gonna eat it its just gonna go to waste. But they dont listen and it pisses me off because they never buy healthy food and then im forced to eat that food cause theres nothing else to eat. They say i should have will power but if theres no food in the house, and she buys fast food what other choices do I have ? I've been working out alot now, i go monday to friday at the gym, an hour each day.30 mins of the treadmill, 15 mins on the bike and 15 mins on the eliptical. Since it's summer I've decided to eat no junk food at all even if uit resorts to not eating anything. I'm sick of my dad hating me, cause I only try to make him proud. I'm sick of kis at school calling me names and talking behind my back of how fat I am. I have this drop dead gorgeousss cousin, who eeryone says when she was youbger looked exctaly like me. They say when I grow up i would look like her if I can lose weight. My mom doesnt understand that if she doesnt let me go out with friends and hang out, play sports and stuff like tht, I can lose weight. My parents are pure indian parents so theres no way to reason with them. Oh and also my dad was once a military officer, so with his family its like the military rule, if you dont listen to him he will yell at you for hours and he does the same thing for my mom. She takes it cause she wants me and my brother to have a father in our life. I dont want to live with my dad anymore but theres NO way for me to stop this. But anyways, i want to lose weight really badly because I can't live like this any longer... Please someone help? It will be really appreciated
