question: Good morning Dr. David, I have a younger sister who got married 7 years back. has two kids, elder 3.5 yrs old and the second girl 1 month. There is no peace in their married life, my sister is a kind of short tempered, unwilling to accept her fault / forgive others. She is not having any friends from her school days, for her everybody on the planet is bad except her. if we try to correct her she cries, sometimes she bluffs whatever comes out of her mouth, using bad words, hurting someones feelings but when we ask her she will refuse saying she never told that. her husband has become helpless due to my sisters frequent misbehavior with her in-law. there is no communication between them at all. my sister blames them always. Dr. is this is related to any psychological problem? Please guide me, I lost my dad within 1.5 years of my sisters marriage, now my mom is under depression and I do not want to loose her as well. if I talk to my mom anything about this sister my mom also supports her. please advise me.....please.....
