How should i feel about this?

okay, so my whole family is really tiny. my mom used to be the big one but then i dont know, she like got really tiny. i used to be the same way. i am still really short just like my family but im the biggest as in weight wise. well, im like 131 punds and 14. yes i know i am chunky, but i used to be really tiny and small and anorexic. i wouldnt eat anything for weeks ata time. i wanted to be like my family and be small and little. well, my aunt and her boyfriend came and visited. when they walked in, we were all standing there. and out of nowhere they go who are you. i was like, its me your nease and then my aunts boyfriend goes geez, girl you got some meat on you-you looking big! and then he looked at my mom-who i said lost a lot of weight and goes, porki pie must be eating all your food! and then hes like look at that face-its so....chubby! and everyone laughed and everything thinking of it as nice.. but, it hurt my feelings. like i said, i did gain some weight,but its better than what i was before-which was 60 pounds and 13 years old. but now, i feel like a pig because everyone in my family is like 5'0-5'3 at tops (except for the men/boys) and weigh like 80-90 pounds and..
