I feel so alone.. Why

`

I know i'm not alone.

I know my boyfriend love me.

I know i got supporting friends.

I know there is people who love me.

But still...

I feel alone.
I feel my boyfriend start to get tired of me.

I feel my friends don't support me.
I feel there isn't people who love me.

How is it possible?

What can i do with it?

I want to block myself out from everyone and everything.
Mabye that's the best ... ?
