Do you ever feel alone even if you're surrounded by lots of people?

Like in school, you're with your "friends" but you can't help feeling like they're hiding something from you or talking behind your back.

Because that is what I am experiencing right now. And it is not paranoia or something because it is so obvious.

And I'm like, why is it always like this? I am being a good friend to them like always... But people just can't seem to understand me. Everything .
