Why am I getting ugly?

because you are 13 !! every one looks ugly in that age !! wait til 16 and you'll look absolutely HOT !! ,, just give it some time !! ,, ! in thirteen your nose gets HUGE !! your hand gets so LONG that can reaches your knees lol it's normal especially for boys ! so it's fine ,! it's just that your body is rebuilding to a grown up man ! so .. am sure you'll look hot ! ..
