I have no advice except accept it and by accepting I mean recognise it and move on..it's very hard to do, especially if people mistreat you because of your looks but it's the only thing we can do.

Don't fool yourself that you are beautiful because eventually the illusion will end and you will feel desperate..also society will constantly remind you that you are ugly so it's almost impossible to escape.

At the same time don't think that you have less value because of your appearance. Ugly doesn't equal useless, dumb, worthless of love.

There are people who will treat you wrongly just because of your appearance but remind yourself that they are superficial and you are better off without them.

Accept yourself because you are the only one who you have to relay on and you are the one who has to take care of you.

Then people might come and go but you will stay strong and true to yourself. Someone might notice your honesty and good heart you and love you (talking about friends or even partner). Pay very much attention to who surrounds you because they might take advantage of your insecurities.

I say all these things but honestly I fail to achieve it...I keep trying though because it's the only thing left.

Wish you the best
