A very sad evening

I found out around 9pm my time tonight that my paternal grandmother passed away last night shortly before 8pm.  I have spent the past three hours trying to get a flight home but have been unsuccessful.  The timing is just too tight, as the services are on Tuesday morning.  I feel so much guilt right now and even though I know I tried really hard to make this work I can't seem to shake this feeling.  I know people understand my predicament, but it just doesn't feel right to not be there.  

I love you grandma!!
