A thank you note

Please read through the paragraph and make corrections were necessary. Thanks.

They say, "Everyone comes to the world on a purpose." I don't know of mine, but I'm sure one of your purposes in the world is to help me out when I'm in a difficulty, ease me when I'm suffering, guide me when I stray, and make me feel cared for and valued when I feel lonely and deserted. I know a simple 'thank you' is not enough for what you did for me, but your greatness won't look down at it. Thank you so much for everything you did for me out of your love for me.
