Help!! my uncle is stuffing me with food so i can get fat!! what should i do or tell him :((?

Ok.. the reason why he's doing this cuz he thinks I'm anerxic and he thinks I have anemia. First off last week and 3 days I was 140 pounds. (14, male, 65 inches high) and now im 145 (close to 146) pounds!! Uncle said "son 5 months ago you were 175 pounds. I'm gonna feed u all this food and if u don't eat what I tell u to eat, ur not welcome in this house and ill send u back with your mother at Arkansas. And u won't eat for a day. So eat what I tell u to eat so u won't have anemia" I say "but uncle I'm not anemia cuz I have a medium frame cuz of the loose skin I have!! Just let me stay this way so I can workout and look good" "your working out*!? Great! So I can stuff you with more food and junk! :)" Idk Waht to do now :(( its barely been a week and I weigh almost 146 pounds.. if this keeps up im going to weigh 160 pounds and my mom will come pick me up from Arkansas! (U see I'm spending my vacation in Texas and I don't want mom to waste her work time picking me up from Texas) help.. sometimes I wanna throw up cuz I have to eat 7 corn tortillas, 3 chicken breasts, 1 small sausage, 2 large ear of corn, almost every meal!!! And I usually eat 3x more than Waht I eat. I usually count up the calories and I end up eating 3050 calories and 60 grams of fat and 11 grams of sat. Fat! :'( help I have a stomach ache. What should I tell him cuz I don't have anemia -__-
