Weight, really bothering me

I'm 17, 6'1 or maybe 6'2 and 200-205 pounds. Yeah, I'm a giant for a girl. My friends are 5'4 or less, and most wear size 0 jeans. They complain. I would cry to even fit into size 14s. I have a big butt, and carry most of my weight in my hips and thighs. My doctor says it's healthier that way. I lost over 30 inches last year doing Brazil Butt Lift, and I have kept most of it off. I just get a little pudge at the bottom of my belly from time to time. Still I'm not happy with where I am. All my friends with these perfect bodies went swimming today and asked me to go but I wouldn't. I actually sat down and cried because I feel so self conscious :( I just don't understand how they can be so inconsiderate. Maybe they aren't trying to be.... But it hurts...  They don't know how it feels to be the fat friend, and I can't explain it. They always tell me I'm not fat, and I know I look way better than I used to. I'm just ranting I guess. Does anyone else ever feel the same way?
