<human>: Together 2 years.  I'm 31.  My girlfriend [26] has two childhood friends with whom she is very close.   A few days ago one of those friends was in a car accident and has since been in a coma in an ICU.  From what the doctor said it is likely that she will have permanently reduced cognitive function.  An MRI will was performed tonight and tomorrow the doctor will have a better idea of her projected mental state at that point.  Aside from the head trauma, she is relatively okay physically.  

My girlfriend is taking this very hard, and I'm not sure what I can do to help.  I am afraid of what might happen if the doctor has really bad news.  I worry that she is heading towards some type of crisis of her own.  She is spending a significant amount of time at the hospital.  Her other friend is there sometimes as well.  She sits in the hospital room and reads out loud or plays music for her friend.  When she comes home she spends her time looking through old Facebook posts, pictures, and going through her old journals.  She's not sleeping very much and when she does come to bed she lays down and sobs uncontrollably.  Often during the night she wakes me up and asks me to hold her while she cries, which I do.  Sometimes she tries to be strong emotionally and sometimes when I interact with her she is distant and forgetful about things.  She stares off into the distance with a glazed look in her eyes and when I attempt to interact with her sometimes she looks as if her eyes have trouble focusing and comprehending what she is looking at.  She says she feels like she's living in a surreal world.  

Are these signs of normal grief?  What more can I do to comfort her?  I go with her to the hospital when I can which is not often enough because of my work schedule.  I tell her try to be hopeful and offer other words of encouragement but I don't think that helps.  I tell her I love her and try to show her the same as much as I can.  What else can I do?

Can you summarize the given text in a few sentences?
