What should I do with my life?

Hai! :3 

So, I have rejoined spacehey recently, 2\3 days ago, and I noticed that almost all of the users on this app\website are grown ups, while I am 15 years old. I've been reading a lot of blogs and noticed that everyone has their dreams clear and knows what to do with their life, while I am still trying to figure out what I really like and what I am ok with. I live in Italy and I am in the first year of High School, the school I chose specialises in foreign Languages, and I am currently studying German and Spanish (and Latin but it freaking sucks).

For most of my life I've been the "art kid" or the "anime kid" in my school, and generally considered weird from most of my classmates and people my age. Now that I am in High School I noticed that my current school is filled with people like that so I wasn't worried about it too much. Having started the second semester tho I realized that, although it seems like it, I am not like my classmates or anyone, apart from like 2 or 3 people. 

I really like the idea of drawing stuuf, and I have a sketchbook, but I haven't been drawing on it because I just forget about it and everytime I draw something I just end up not liking it. I have several different interests with a similar situaion, like playing videogames (I still have to finish 3 different games), reading, making music..

Almost everyone at my age knows what they want to do with their life, but having this problem with almost all of my interests I don't even know if I like doing what I do. My only hobby in which I don't have this problem is volleyball. But I don't really see it becoming my future and questioning my gender is something that would only make it worse. With the school which I'm attending rn I don't know what I could do as a job. I could be an intrepeter but I would be too anxious to do that, and oyther then that I can't do that many jobs, so I will probably go to University even though I may not like it.

Something I would see becoming my future is song writing, I would be happy to do that but at the same time too scared to perform, so I really son't know what to do rn.

(sorry for the long text!! If u read it all thanx! :33)
