Dear Asirat 7obah
I have read your poem twice and enjoyed reading it every time. The thoughts and images were clear and simple, and the emotions touching and tender. It's clear to me that you worked hard on choosing your words and images and it has paid off. Nonetheless, to make this poem the perfect one it should be, I suggest you correct the grammar of the following phrases
I saw a star in the sky
I knew there was someone who cares
Now I know that I'm not alone
And she told me honestly what to do
I gave her my thanks and she smiled at me
She promised always to do the best for me
I slowly closed my window
And I prayed to God
You see you have to maintain the tense of the verbs in the same sentence. In your case you chose most of the sentences to be in the past tense. Another point is that try not to use the word "AND" too much. In the poem you used it ten times
However, I still think this is a marvelous piece of writing taking into consideration it's one of your early works
