i feel like i have a few things wrong with my face (i could be seeing wrong but idk)?

everytime i see myself, i see: big lips, a big chin and a round face but the thing is, i've asked my family and girlfriend, all of whom i trust, and they say that i'm totally wrong also, if these things were true, people would've made fun of them i think (because there's a few people who hate me and are low enough to make fun of how people look) i just don't believe that these things aren't true, how can i? no one has ever mentioned these things to me, so idk i dont want to post a picture btw, sorry please help me with this awful situation
