Cursed or Blessed?

A gust of wind blows through
My leafy mane
All day I stand in sunshine
Or in rain

Patiently I wait
As time goes by
For that oh so faithful day
That I may die

For now I shall enjoy
My current friends
And I shall lament that day
Their lives would end

Cursed or blest, I've no clue
For I live long,
Longer than some or more -
What is so wrong?

My friends come and they go
Like night into day
How sad it is to be me!
What am I? - a tree.
