I am needed, but not wanted. Most people hate that they need

I am needed, but not wanted.
Most people hate that they need me,
And wish they could just push me away.
They try to.
But I stay because they need me.
I just need somebody to want me.
I want someone to tell me to stay,
Not just because they need me,
But because they want me as well.

I just need to be wanted.
