Here's my input. We are diverse here on this site so you might get many conflicting ideas, so pick and choose. Anything that helps you.
Also, your English is beyond just good. It' s better than mine.
I know local college students who can't even complete a employment resume that makes any sence. English sucks as a language to learn to write. The few errors you have written are very minor. I probably have more. Folks on this site have excellant verbal and written skills. Don't worry.
So to help with your depression first. Being proficient with speaking English as you are is going to be such a help to secure your university of choice and later employment that you actually want and that will pay well. Your school instructors can guide you through more smoothly than most to find out what you can best accomplish.
With the economy in your country what it is, this is on all young adults minds, or you'd hope. But nope it's sex and getting f....ked up. Gotta love the 'teen years'. Don't try to be popular. Never works for us. Pick out someone u like and feel somewhat comfortable to be around and be genuinely nice. If others think you are weird now thats not going to change in the next few years. Use their social 'unskills' to learn how not to be. Girls, eee god. Good luck.lol
So you need to learn to be a good if not great ACTOR. YES, the next 50 years, 'your on stage', Aspie or not, get use to it. It's a ***** and not real healthy for your brain but you have to make a living and have a uncomplicated social/ sex(yeah) life and be happy. This is so wrong in so many ways but your stuck with a brain that others will never understand. It's a survival tactic that has kinda worked for me.
For me not knowing nothing of why I was 'anti social', as my mother would say, Iphones weren't around but my bedroom was, so that's where I went.
With you family friends around start your acting by 'being' interested in what someone is saying. Can't believe they call you 'gf' when you are gaming. Practice with strangers, maybe tourists if in that kind of area. You are young enough to get away with alot. S long as you a nice and helpful. Socializing takes practice. Socializing is acting for us.
Put the Iphone in your pocket making sure that person sees u do that and then look at them, kinda, and maybe pay attention with an approptiate reponse. They'll think you are interested in what they are saying though you're probalby not. You will get good at this as I see you are quite crafty already. This will actually help you on many levels.
Don't try this on your school mates or you'll get the **** beat out of you. They will require a different style of acting.
With your mates, stop trying to be cool and just pay attention. Pretend you're interested. Ask question about them. Aspies never think to do that 'act' and that a big problem. We look like we don't care. True but we should know better, we are smarter.
With girls, good luck. You are going to be misjudged and misjudge the rest of your life with the opposite sex, get use to it.
Forget about befriending a girl in school older than you. You need Brad Pitt skills for that and look like Cristiano and play futball flawlessly as well and have the wardrobe etc. etc. In ten years, that will be your objective though.
To make friends with your male mates in school and since you a perceived to be smarter, offer in your learned special 'acting' ways to help the nicer ones in any subjects they need help. Again be sincere, but cool sincere, u know what i mean.
We Aspies have limitations, at least limitations that NT' s think we have, but at your age and now knowing you did not cause these limitations(differences), work on them a Smart way.
You want to be accepted, but make it on your terms. And for sure dont beat yourself up on this.
School SUCKS. You have a few years to go. Don't get caught up in the Vodka frenzy your friends are doing. And don't tear down your heritage. The french kids think they are gods, the Spanish the same but have a lisp lol, Italians cook well but live with their mothers forever.
Be yourself when it counts and 'act' when it is necessary.
Too long of a reply and even I had to spellcheck.
