Help!!!!

While I was doing dishes a little while ago, Rachel came to me and said, in a clearly shaken voice, "There is a bug in the shower." I thought, "oh, brother, there's a daddy long leg or some kind of little bug."

I was wrong.

Oh, how I wish it had been a daddy long leg. Or a variety of other bugs. However, when I went to investigate, I found this:

EEEWWWW!!!! It was about 2-3 inches long!
Where in the world did it come from?
We have never had these kinds of pests!
And I pray we never have another one!
Please, dear God, PLEASE!

Anyone who knows me knows that I have a bug phobia. I have been known to leave my children to get away from bugs. I know, I am not going to win 'Mother of the Year'(unless worst is in front of it). Anywho, Tom was not here and I was stressing out! He finally got home a few minutes ago and I told him not to come in the house without Raid.
Thankfully, he disposed of it.
I could not watch.
I don't think I will sleep tonight.
It feels like they are crawling all over me.
I'm totally freaking out.
