Mommy is leaving me again at this awful place. I hate it. I know she thinks that is better for me, that she was advised to to do, that I will grow stronger, that I will be surrounded by girls my age, that I will be better nourished, but everything is a lie.
I can not stand the food, so I don't eat it. I miss Mommy so much. Why can't I stay at home with the new baby? Why is the new baby more important than me? They don't even let me keep my letters, so I can feel closer to them. The only thing that makde me happy is that I made a friend but all of a sudden she was taken away to other place.
Deep down, I know that I can't burden Mommy with all my silly feelings. I have to be strong for her and her baby. I will not complain. I only wish Mommy could understand that the only thing I need, the only thing I desire is a family, a house, love, hugs and attention. I hope Mommy comes soon to pick me up, as it is the only thing I crave for.
