I would say that, maybe you should rethink how you look at your situation. You have family, siblings (and i know siblings can be *****) and you are still young. There is always time in the future to go out. Also id point out that most older generations never had FB, insta or anything like that so had to grow up in silence or walk round to their friends house. Being connected is great but it is utterly **** for your mind. Staring at fb for hours watching everyone else's lives roll past can make you feel soo much worse because you just sit there thinking about how bad your life is in comparison to theirs because they are out and doing things with people they like or are friends with. Friendships go both ways, reach out to people and see if anyone ewants to hang out for a while or go do someting. If not, then find something for you, spend time with yourself and be your own friend. Growing older it will only become more apparent that you will have less friends, its a hard pill to swallow but if you want to be an independant adult then you need to learn this lesson quickly. Think about what your hobbies are? do you like to read? goto the gym? fill your time with those instead. Also if someone is being a **** to you because you got into uni and they or theirs didnt it's because you worked hard and they haven't. You are no better and no less than them just more determined. People get ratty when someone changes, but you have to keep in mind it is your life and only you have control over that life. Keep your chin up, and life will find a way to work itself out eventually.
