I have often wondered if my sister is Bi polar. What are the symptoms? My sister seems to have alot of mood swings and gets very angry when her children do not do as told. However, my father was the same way growing up and I was never sure if it was just his personality or if he had bi- polar also. She makes up stories that never happened and makes everyone feel sorry for her while believing these stories. And when she drinks alcohol she goes in rages out of no where. Does this sound like bi polar to u?
