Can't handle rude people

I have no tolereance for rude people lately and I am starting to be mean :(

First, My MOH had to call EVERY guest for my shower because NOONE rsvp'ed (yes, all contact info was correct).

Then guests came and ate and left with no gifts.

And a younger cousin brought a friend, who was cheating to win all the prizes and quit frankly was obnoxious overall.

(which I can accept both of those, but my girls paid for this and it was my CLOSE family).

Wedding RSVP's are coming, with (of course)guests not invited.

So now I snapped (and scared a few people) getting lunch today because this b*tch kept pretending to look at menu and eased her way in front of me then tried to go first. I hate that!
Also notice it's almost 3pm and I just got lunch. Why? Because someone decided when I was walking out the door they HAD to stop to discuss immediately a job that won't even need to be looked at for 2 weeks!

I guess maybe I am starting to get stressed.....
