>>8220369420 is still very young and a lot can change in the future.
>got called down syndrome a lot in schoolWho cares what some teenagers think? They're dumb, insecure and don't have a developed brain yet.
>idk how to work out my faceFace wash, creams and if possible, make-up (though it'll have to come off at some point) I'm sure you're some guy's type or at least looksmatch.
Worst case do plastic (it'll cost you, though).
>fundamental personalityPractice practice practice. Go to social meetings like cons and join the activities, you'd be expected to be a bit nerdy and awkward. Go on dating apps and you're gurenteed to have a small harem of simps you can practice on and filter out the best one to date or befriend and evolve your personality via experience. I had a horrific personality at 20, you grow up as a person; but you have to get out of your comfort zone and dare to do new things. Not being self deprecating and having a confidence and self-love can take you a very very long way.
