sometimes I am just not in a happy place

Right now I am so angry I could spit. Dad's footstone was supposed to be at his grave by now, and is it?? NO. We have scheduled the unveiling for this coming Monday, and if it isn't there by Friday we'll have to reschedule. I just don't want to have it in August. Call me superstitious, but the last unveiling we had 3 days later my dad had his massive stroke. He died a week after mom's unveiling. The only realistic date we can have the unveiling would be probably on the 18th of August. I have had enough of a difficult year, and this isn't what I want. I am seriously going to lose it.
