How can I get my family to be more accepting?

I too come from a poor family, dont worry, your sister, well she is your older sister, she will be like that no matter what but she still cares for you and not old enough to relize. Your parents, are your parents, they accept you no matter what, they will feel even worst then cant afford to take care of you. That will be a disappointment to them and will be extreamly hard on them too. This is how most families are when they are struggling and need money, my family goes through the same.
