What is the world coming to?

Ok so i'm going to make this quick and try and keep it as simple as possible. I'm 16 year old and i'm a bit depressed, i'm not at the stage where I want to cut my wrist but i'm afraid it might come to that if I carry on experiencing this. Ok so the problem is that I feel quite old not old as in I feel tired and I make involuntary noises when I bend down to pick something up, no I mean old as in looking at other 16 year old s and saying to myself that there is something wrong with me. I'm talking about the clothes they wear, the music they like, the way they speak and other things. I see other kids wearing all these designer clothes like Armani and G star or whatever, I like to dress up in a shirt and pants sort of outfit almost like a suit. Then there's the music, I love jazz and clical I also like some modern music that comes out nowadays but, God when I hear the music other kids are listening to I feel so depressed, like N-Dubz for example, what on this earth has the power to hypnotise the world's youth to like these *!>@s. Then one thing that really gets on my nerves is the accent and language these kids use. Sorry I forgot to mention i'm from the UK and the kids over here are either jumping off bridges or obtaining ASBOs. Now you may say get on with your own life and ignore these people but I can't I mean you have to think about the future, for example in 30-50 years, where will these people be and what will they be doing. The older generation look down at us kids and laugh at us, This really embarrases me as I can't do anything about it. I'm just worried what the future will bring. Please tell me this will all p as we grow up. (Sorry this quesiton is a bit long winded but I tried to fit everything in, i'm not even sure this is a question)
