<human>: My girlfriend's sister passed away years ago and it effected her really badly, causing her to become depressed. She's no longer depressed but she doesn't talk about it very much. She expresses that she does want to talk about her sister more but she doesn't really remember anything about her so she doesn't know what to say. Her family is not very supportive and they don't talk about their emotions with each other so she's too nervous to ask them about her sister. She's mentioned feeling like she may have repressed some things which were too hard for her to handle. 

She did recently start seeing a therapist but still hasn't opened up much about the subject. When things started to get serious she canceled her apt. and stopped going. She says she feels more comfortable talking to me but I honestly don't know what to say or ask. 

So I'm basically just wondering what I can do to help her bring back some memories. What questions can i ask her to help her open up? They do have to be very specific because shes doesn't give me a lot to work with and if I ask broad questions I usually get short or vague responses.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My gf can't remember anything about her sister since she passed away and wants me to help her start talking about her but I need some advice on what to ask to help her remember.
