Am I worth more than this?

Is this envy? Is this jealousy?
But my heart yearns for more than I now have,
Everybody has somebody, but me, where?
Where have my best buds in life gone to when I felt lonely,
Deserted in this ice cold fire of friendship,
It's warm, yes it is, but it freezes me to death.

My dear friend, I do envy you,
People flock to you, even I do myself,
How I wish I was worth as much as everyone else,
And even more so to myself and whoever is willing to take me into their lives,
But here I will stay, just hoping and wishing my value is way more,
Than my words now condemn me.

What am I to you?
I'm ever just a mere friend,
That disappears as soon as a bird makes its way to the south to hide its wings from winter.

And what a cold horrid winter this is.
