What do i do ?

that's pretty common for your age. i would suggest you work on your ability to make decisions, since it seems to be quite weak. this is a frequent case in teenagers though, and can only be solved by you taking real, mature responsibility for your actions. try to acquire responsible habits that will shift your overall take of action in life towards the goals you desire or the path you aspire to follow. don't go too hard on yourself either. smile.

I found inspiration in youtube until I became addicted to facebook which is really bad, it made me sad.. But I got to learn a lot of trash no sht give afuk about.. it made me realize what I can do in the future.
You can get back to fb, (or twitter/both) using another acc with none of your friends in there so you don't get to see their posts and they won't see yours then

you can start by reading articles from facebook posts of '(unless you hav the actual thing, then that's fine) time' and 'ted' then 'buzzfeed' (and its babies(like food)) then 'iflscience' and then liking fb pages of viners unless you have your own vinnyl acc.. + the fb pages that features your fave stuff/hobbies/learning/music. You can get back to your original when you get back on your feet.
Then there's youtube where you get to search a lot of things and mainly hobbies and things that make you smile.. and it can be a very useful tool for things you want/need to know.. but the comment section.. please.. don't.
And I really like youtube because of the community, the people there.. what they share with us.. and you can also watch gameplays and stuff and well, arrange a schedule and make plans, use your money wisely, make budgets.. have a planner, have a maintained well diet balance, eat well and excercise. Stay away from drugs and alcohol and simmilar stuff. Turn off the technology if it is a bothersome, I insist you take leave (like a month/year/for how long) Go out, learn new things, meet new people, talk to them, build a strong relationship, learn to enjoy peace, plus religion helps you find your path and ways so if you're atheist.. then I don't know, but I know they usually have mental disorders and end up really messed up.. Listen to music and do what you love doing. Hope this helped..

Take acting lessons if u wanna play on life's big stage...its all just a big ole contrived stage play and you won't even fathom, at this point, that there is a door..exit stage left.
