I really need to stop doing this to myself!

I secured a hard to get lodging reservation for a three day event this weekend. I was really surprised I lucked into it. I knew that my mother probably wanted to go as well, so I told her she could share. To be honest, I thought she would be working. I assumed if she did want to share, it would just be for one night.

Well, she's NOT working. She wants to go ALL of the days. I am so irritated with myself for offering this. She drives me crazy if I am around her for more than an hour or so. I was really looking forward to this event, but now I am stressed out because I have this specter of her hanging over my head. She's already annoying me with text messages.

I am going to try not to let her get to me, but I really just can't stand her lately. She is very passive aggressive/annoying/martyr-like.
