Depression

how to tell my sister is depressed and not lorsakoff?When she is with me she is non responsive yet if someone else is there she is smilling and laughing.The minute im gone she is back to smilling.All she does is sleep.She has been in the hopsital over a year.She seems to be stuck in the year our mother passed away 2004.She doesnt make up things any more.But seems angry with me for a reason i dont know.I need help.I had to mourn my mother in 2004 and do it everything i visit my sister.

Wow, guess this page hasn’t seen a lot of traffic!

What do her doctors say and has she had any testing?
