My sadness end?

Now is the end
I lost all my friends
It is so painfull
'Cause I was such a fool.

I regret what I've done
But they are already gone
Now is too late,
I made a big mistake.

Because I was a worm
I always been alone.
I can't say I'm not,
I know I desurve that.

It doesn't matter what I feel,
My loneliness can not be kill.
I know a single thing
Wherever I go just sadness I bring.
