Life sucks and then you die!

Why is my family so self absorbed and selfish? If I had money, I would move away and leave them all behind. They act like I am such a burden to them. If I ask for a ride, I get "Why can't so and so take you?" If i ask for a couple of dollars for my medicine, I get the same response. All I ever hear is "Mom, Can you clean the kitchen, Mom, can you do this, can you do that, watch my kids for me. I never asked my mother to clean my house. They never ask me if I would like to join them for lunch or lets go out to eat.  I am never included in any family activities. I am so angry and depressed and sad, I don't think I will ever feel good again. There is no joy in my life anymore. Is this all thats left?
