Your journey and that of your family must have been a difficult one. One of the most important things you can do is educate yourself on your sisters condition and learn to set boundaries so you do not let it effect you in a negative way. Where is her son now. He must be rather traumatised by his mothers unpredictable behaviours.There are many respurces on youtube on relationships with people with behaviour disorders. Stay strong and look after yourself. X
