I have BPD and my emotions and feelings are so out there sometimes. I have a daughter who is mentally retarded and she feeds off of how I feel that day. Sometimes its so hard to be happy and positive for her. She does not understand that I am not mad, or sad or depressed because of her. I am learning to regulate my emotions so how do I help her understand? I may say something and she thinks I am being mean or rude. This is so hard to even say what I am trying to...............
