Princess House Party

I'm having a Princess House party Wednesday.

Their site is here: http://www.princesshouse.com/EN/Home/Index.asp?11%3A33%3A17+AM

I hate having these. I used to have parties all the time. Tupperware, Princess House, Pampered Chef... I even sold charms for a while through Perfectly Charming.

My issue is that when people don't show up I take it WAY too personally. Like they really don't like me or something. Which, in reality, I don't think I worry too much about it in everyday life, but when you invite someone to your home and they don't show, it makes me sad.

Am I alone in this feeling? Please tell me I'm not a complete lamo.
