Tree without leaves

It feels like a tree without leaves,

No one appreciates me,

Too scared to make my own food, Even if there is photosynthesis,

Too dark until no one saw me,

Trying to make oxygen for someone breath, But I also don’t use carbon dioxide much,

But

Thanks to the wind even though I couldn’t feel it, But it was always with me.

I think I'd better be cut, I'm too useless for being a tree
