Children in orphanages?

You absolutely can. Who cares what your home life is like? That is completely irrelevant. What matters is what you want to be and how hard you want to work to achieve this! You just have to have faith... surround yourself with good people who will support you emotionally and work your off. It will happen. Change can be scary, but without change there would be no future... so even though it's normal to be scared, you need to push through that and do what you need to do to better yourself! Good luck!
