Feeling Fat but i’m actually not.

I know i’m not fat, i’m a twig. but sometimes when i’m bloated i feel like a FREAKING BALLOON! so when i well my friends: “hey, i feel soo fat” they always just write it off as me looking for attention and it’s super annoying because i’m really not looking for attention!! i just like to confide in my friends when i’m not feeling 100%. i just don’t know what else to do to tell them how i’m feeling. even when i explain what i mean they just say “girl, i’m wayyy fatter than you” and of course they aren’t actually because all of my friends are super fit CHEERLEADERS WITH ABS!!!! so idfk what to do. any ideas????
