I feel like Alien

I don't know why, but I feel myself like an alien.
Like nobody has the same thought as me (don't count my BF).
Sometimes I wanna go outside the crowd and be alone
But I feel more sad if I am alone.
So I just hang up, striving with everything that contradictory with my mind and perception.

Is it only me or what? why I rarely get people who support and agree with me?
Most people fool me down, if I try to speak up.

What I have to do? I can't be myself.
I should be what they want I am gonna be.
