I'm Terrified

I know that this sounds stupid.  You'll probably all think I'm rather pathetic.  But I'm having a serious problem right now.  I am scared to death.  I'm scared to go into the shower, I'm scared to walk on the carpet, I'm scared to reach behind things, I'm scared to sit on the couch.  Right now I'm sitting in the middle of our bed safely away from the walls and edges of the bed.  Why?  Because I'm afraid of spiders.  Yes, all of this hysteria is just because of a little tiny bug that's 'more afraid of you than you are of it'.  I don't buy that saying.  If they were as scared as I was, then they'd be curled up in little balls in a little nook somewhere.  I once had a breakdown after a huge spider crawled out of my sock drawer that I'd just been digging through.  I would sometimes refuse to sleep in my bedroom for a night or two after I saw a spider in there.  This week I've seen at least 4 different kinds of spiders in our house.  About an hour ago one dropped down right next to me when I was sitting on the couch.  One of the nasty ones with the huge butts and long skinny legs.  And there's been the big chunky black ones, and the light-colored ones that look like they have pads on their feet, and the mean ones with sharp-looking legs.... I'm seriously considering moving in with the inlaws for a while (I mean really moving in.  Taking Blake's old bedroom).  I don't know what to do about this.  I'm scared and I want to cry and I wish Blake was here to hold me right now and comfort me and I want all of the spiders to just die.  Where I won't find their bodies.  Dead spiders are pretty creepy too.  But at least they can't move.  Blake squished one of the spiders on the carpet with his bare feet (!) and I haven't stepped in that area for days because of it.  I'm seriously so sick of this.  I'm so scared I can hardly do anything.  The laundry I washed  is still sitting in the hamper in the front room because it's by the couch and I'm afraid that there's a spider in it.  I'm so paranoid, I keep feeling like there's something in my hair or crawling on my leg... And I don't know what to do about it.  Maybe if I just coat our house in poison... I know I sound so dumb, but if you knew the fear that I felt then you'd feel this way too.  Something has to change.  Now. But I don't know how.

PS Forget the harpies, I'm pretty sure the 7th circle of Hell is filled with spiders
