I feel like I don't belong ?

Now, I know this might sound a little strange, but even though I'm extremely popular, I never feel like I belong there in that spot.

There are all kind of people around me every day and I'm kind to the looser (Sorry, I may also call them nerds or unpopular) kids in school and talk to them about their problems. I'm caring and understanding with them because I feel like them deep inside.

They tell me that they feel like they don't belong and that they are not as popular as I am, and I feel like I'm in exactly the same situation.

When I'm hanging out with the other popular kids and I listen to their conversations and their gossiping...I just hate it, it all seems so meaningless to me.

I feel like nobody understands me and how I look at things.

For example when someone is bullying some kid and I ask them if they knew this person had feelings, too and they say: who cares?

then Í feel like aaaaaa, I wanna beat the crap out of him....

In conclusion you could say that I'm standing in the middle of a huge crowd and NOBODY sees me for who I am only for what they see on the outside.

I'm not that girl, I don't wana be part of this world, most of the time I just want to run away, but I got nowhere to go away to...

Am I weird for feeling like this?

Is there anything that could make me feel differently?

Please, I would really appreciate a detailed answer...

PS: I'm 15 years old and I go to a school in Germany, where I'll hopefully graduate in two and a half years...
