history: My colleague is waiting biopsy results. I am worried for her.  I have a wonderful colleague who is awaiting biopsy results. It's so concerning. She's a lovely person. Oh_comma_ dear! You must be anxious for your colleague. I really hope everything comes out alright.
current: Same here. I'm trying to do everything I can to be supportive while trying to distract her from worrying. 
next: You are a good and caring friend. She is lucky to have you.
