You're my best friend

When you are sad, I will dry your tears.
When you are scared, I will comfort your fears.
When you are worried, I will give you hope.
When you are confused, I will hep you cope.
And when you are lost,
And can’t see the light.
I shall be your beacon
Shining ever so bright
This is my oath.
I pledge till the end
Why you may ask?
Because you are my friend.
