I don't really have any advise just wanted to say how intune you are with how she might be feeling. I wish more of my friends were like you and would stop trying to commemorate my loss. 6months on I am still a conplete mess which is only made worse by friends bring up what has happened when all I want to do is dwell in my own self pity.
I hope you find a nice way to let her know your thinking of her. I am sure knowing how it feels and be so intune with how people grieve differently you wont add to her heartache.
