This is the first time I've ever had to consider doing anything like this and just can't seem to comprehend what is happening.

Last month my mother was diagnosed with Pancreatic and liver cancer. Since then it has spread into her bowel aswel. (She was still doing her day to day jobs and driving etc.). However all of a sudden in the space of approximately two days she has gone from that to being in a hospital bed and being told she has only a couple of days max.  
 

I suppose what I'm asking is if anyone has any regrets about the passing of a loved one in the last few days/hours/minutes?  
 

I am 19yrs old and can't help but feel guilty every single time I leave her side.  At the moment she is unaware if we are even in the room and can't feel us or speak to us.  She is simply laying there groaning in pain and just about breathing.  It's heart breaking.

Any words of wisdom would be so greatly appreciated.
