I Don't Trust Easily Anymore

I was raised in a bad home and was from my mum I was only a accessory for her to look good. Because I have always been small for my age they would try passing me as a younger kid to get things for cheaper or free. But when home I was just a waste of space. Before Christmas last year I was put in hospital and taken away from my parents and put into foster care. I’m currently with a nice family and they have never done anything to hurt me but I feel like they don’t care for me and want to use me in some way.
