Cheer up, anon! /adv/ and /vp/ lurker here
An Unattractive face is treatable (unless you were born with a deformity or lost part of your face in an accident) you can make yourself attactive again.
First of all practice good hygiene, shower daily, cut your hair, shave and brush your teeth, if you can get a whitening on your teeth you'll be amazed how suddenly you want to smile for everything.
Messure your face to evaluate your symmetry, if there's a part in your face that doesn't seem to match the others wear an accesory to counter it (ie. glasses, a scarf, a hat, get brackets etc.)
If you are fat, start a plan of excercise, just don't tell anyone, start up with your own motivation and when you start getting results, people will notice and start asking you.
And to keep this /vp/ related use your favorite pokemon soundtrack to keep you motivated
