Something doesnt seem right

Today Im at work and my boss seems to be prying into my personal life. She has had a weird attitude the last few days.  Huffy and short tempered.  I have ask her if there is something I did wrong which she replys No.  

I dont know whats going on..Im just trying to ignore it and focus on my work.  The company Holiday party is this weekend.  I told Roomie that I would be going to help only and that I am only staying an hour or so.  My boss was adament with me to make sure I dont bring someone else at the last minute cause she needs a head count.  It makes me mad and quite frankly I dont even want to go, but, the company is so small and I feel like I need to go just for my job sake.  

I feel like Im free falling still-i thought I had got past all that but Im still as insecure and unstable as ever.  I want to retreat back to my bed and shut the door.  I just have grown so tired of dealing with people and situations.  I hate the holidays:(  1 step forward and 10 back.
