[|Human|] My sister has a diagnosis of hyper mania that she just shared this information with me recently.  I have always suspected that she may be bipolar.  She is 55 years old. Every since we were young children she has always told lies. Now as an adult she lies constantly. I have always just overlooked her lying until recently Ive started to question her on the stories she tells. She almost lives in a fantasy world when it comes to reminiscing bout our childhoods. I just tell her that  I dont remember what shes talking about. Should I come right out and tell her that I dont believe her? What really set me off over the holidays was my sister is a collector of vintage Christmas ornaments. She gave a box of ornaments to my 35 year old son and told him that they were his grandmothers ( my mother who is deceased )  these ornaments were never my mothers!  When I told her that I dont remember ever seeing these ornaments while we were growing up she replied mom gave them to me a long time ago. I dont know how to deal with her anymore. Do you know of any good books on dealing with someone like this?Thank you
[|AI|]  Hello and welcome to Chat Doctor. Thanks for your query. I understand that you are experiencing some difficulties in dealing with your sister. You have mentioned that she has been diagnosed to have "hyper mania", but in psychiatric diagnosis there is no such diagnosis as hyper mania. There is a possibility that she may be suffering from mania or hypomania, which are classified under Bipolar disorder. Regarding the lying, there can be a variety of reasons for this - and just based on this symptom, it is not possible to arrive at a definitive diagnosis of her condition. I suggest that you discuss with her psychiatrist to clarify what her actual diagnosis is so that you will know how to deal with her better. In case the frequent lying and making up of fantasies are due to a psychiatric illness, then it would be best to ignore this and rather ensure that she is receiving appropriate medication for her illness. Wish you all the best.
