Oh Dear.... It sounds horrible. I must say that in sending the step child to live with the good grandma... You have in a sence, punished the child. He is no longer alowed to live with mom, dad, and sister, because of the bad grandma. So the bad grandma is happy now and the step child is far away from his mom. I would have chosen to punish the bad grandma... and move the whole family far out of her house... especially her own son. You see, she is pleased to have her "baby" back even if it means she has to tolerate his new family. She is not keeping you all there because she loves all of you, she only loves her son, and perhaps the baby grandchild. If you want to test her... send dad to live with the good grandma and stepson, and see what treatment you get then. She wouldnt get any better...not even with hapy pills... she would be horrid to you then. It is hard when money is tight, and jobs are scarce. No matter what the situation, I would keep the NEW FAMILY TOGETHER in a happy place, even if it meant that all 4 of you had to sleep on the floor in the good grandma's tiny happy home.
