I am so sorry LittleForgetMeNot. It is hard when the depression is bad. It seems as if everything people say is against you and mean. And you are right, they don't have to stay around you and if they start putting you down or saying mean things tell them they can leave and shut the heck up! You are allowed to feel the way you do and no one can tell you otherwise....but still, their words hurt I know.
Hang in there and know that there is always someone here to talk to
