OK man, seems like your unhappy right now and did some much needed contemplation. You said you came up with:
-Want to have real friends
-Want to experience things with other people than my family
-Feel happy
-Have fun other than forcing myself to play ps4 when i dont want to
-choosing the right career path
-Living in a sociable neighbourhood
-Being self -confident
-Being true to myself
Well let's go through these right, I'm going to colour code them to make it easier to understand., first of all being true to yourself, in your opinion, means what? Being honest with how you feel, being able to articulate your thoughts? Being able to have discipline over yourself? You need to make this more specific, as right now it doesn't much. And once you've figured it out, chase it. Force yourself to be honest with how you feel, meditate if you have to, force yourself to be disciplined and wake up at X time or eat X food or say no to certain things you don't like until it's who you are. Hopefully for the better than the worse.
Now secondly, you'll have to do some more thinking into what this means too man, I mean whats happy? You feel happy for a bit when you buy yourself something new, but you also feel happy when watching a peaceful sunset, when with friends and when you have an 'aha' moment in school. They're all different types of happiness and to be honest none of them are really for the long term, what people call happiness with themselves is called being content. Maybe you want to be proud in who you are, be confident in your abilities or so fourth, but thats not happiness. Happiness is kind of short lived to be honest. Being content brings that euphoria of happiness, but also the confidence and the longevity of it.
Now this is kind of difficult, and for that I'm not gonna talk too much about it, but that's more of a long term goal and for that there's not much you can do other than maximise your options to get into the position where you can choose a neighbourhood for you -- and to do that you'll need good grades which gives you that option. This goal also allows us to realise that not everything is short term completable, and that some things are easier to fix than others.
Confidence is a hard one man, because for some it's naturally just so much easier, and for that it could take you more work. o be honest, it comes with charisma right, so you can't reaaally be one without the other. Now when building either, it's important to know that a lot of people built their confident on the foundations of nothing - simply a fake it till you make it approach. The more you practise being confident in yourself and what you can do, as well as confidence speaking to others, the more it will naturally stick with you.
I think the first two on the list come together, and you need to make more friends before you can have good experiences with them. Now you're almost in college, so that's a clean slate you to mingle. You need to practise in your school right now how to make friends, because honestly man (and I'm sorry to be blunt) if you have only a few friends in Year 11 then you're already behind, which is sometimes just what you need to hear to up the game. Go talk to people when you go back, ask them whats up, join their conversations. It might feel strange and unnatural to do this, but it's also gonna contribute to that confidence you need to build. Practise makes perfect!
Well if you've got nothing to do other than play the PS4, then I'd say force yourself outside instead man, go find a park or a skatepark near you and talk to whoever is there, again confidence building. People at skateparks are some of the most down to earth people you'll meet, go up to talk to them and you'll find out. Maybe you'll even pick up the skating or just chill and watch people and have convos. You'll never know if you don't try -- and if you don't want to go to a park, try a club man. I'm not a fan of clubs, I think they're cheesy, but if it's what you have to do then it's what has to be done -- or maybe pick MMA or boxing, any form of physical defence sport should come with confidence gain too as you see your body and discipline improve.
And finally. your career. That's very personal to you, what do you enjoy, what can you make a job out of and most importantly what do you want to be focusing yourself on for the next 6 years? Going into a study you don't like but has good pay sets you up for failure, and going into a study that's useless also sets you up for bad job security. Consider everything and read everything related to figuring out who you are and what career is for you. Nothing more too it man, it's going to keep you awake at night, it's going to stress you as you get closer to finalising, but that's what life is man, stressful short periods followed by long relaxed periods, if you do it right. Good luck man.
