Although you are feeling really depressed about the loss of your friend, I find it hard to believe that your family doesn't care about your health. I think you might really believe in your heart that no one cares but I don't think that's true. Give them some time. They are your family and they love you. But you have to take care of your health. You have to care about it, even if you believe no one else does. In the mean time just know that there are people in here who care about you and will listen to you without judging you and that you are always welcome in here.
