Don't worry, you'll get through this. Worrying will only make it worse, and worrying about your family bills are fine, that's very kind of you, but every penny they make is for you. I highly suggest to tell them, and you are not a burden, they carry you for a reason, because they love you, and want you to be happy. One way to make you happy is to help you with your problems, trust me. Don't be afraid! I hoped I helped!
