My sister has cut off contact with me , my mum and dad (for the last five years) we have no idea why. as a child she was cold, withdrawn and would lash out without thinking of the consequences. As a teenager she was aggresive (she twisted my mums arm, tried to push her down stairs, and hit my dad in the chest with a spanner, to name a few instances) When she left home she cut off contact. She lies to family members and often twists facts (making up lies, imagining things, ). She appears over friendly (very over the top and sickly) to others. She also seems to be confused about her sexuality. My mum and dad gave us the best of everything, and we could not have possibly been brought up in a better family environment. the fact that she will have nothing to do with us- It is killing me and my parents, and is placing strain on their 30 year marriage. We have tries everything to understand what has happened , but nothing works. We dont know if she has a some kind of illness or not . Please help
