So, I asked my MOH to cancel my bachelorette party.

My family recently suffered a loss - 4 of my family members (my aunt, uncle, and their children/my 2 young cousins) all passed away suddenly and tragically. My date that had been set for my bachelorette was March 9th and that would have been my cousin who passed's 12th birthday. So, it probably will not be a very good day as it is. But along with a multitude of other crap that has happened with the bach. party. I just decided to end it.
There has been alot of drama along with the bachelorette party between my girls, that my bridesmaids and MOH felt the need to call constantly to bitch about eachother and involve me. It pretty much just came down to the fact that I honestly just didnt want the stress of it anymore, and I think its pretty sad that somehow my best friends and family were throwing me a party and it turned into huge stress for me.

I dunno, am I out of line for wanting to cancel a month away? Are my reasons valid? Or should I just suck it up and attend it?
