Ticking Time Bomb

Like I said in my first post, I don't want this blog to be about me ranting and complaining and whining, and I'm determined it won't be despite some of my past posts. I was hoping to do some reading on parenting and marital relationships to find out some things to experiment on, but, lets face it, I am way too stressed out right now. I don't handle stress well, either. I usually withdraw from the situation and let things--laundry in this case-- pile up around me.
My whole house is one giant ball of pent up frustration just waiting to explode. My sister is getting married in a month, my husband is graduating next week, we need to move all our stuff out of our old place and drive it cross country and put it in storage here until our house is done, we are building a house, one of my best friends is going through a horrible crisis and I'm dying that I can't be there with her. Plus, I live with my mom. Living with your mom when she is trying to plan a wedding is like living with a hydrogen bomb. I worry so much that any little mistake I make will be more than she can handle and she'll just explode and take us all down with her.
Here I am going through my own anxiety while watching my mother go through hers, watching my sister try to plan her wedding, and my husband trying to wrap up school. It's amazing we haven't killed each other yet.
I have to admit I have considered seeing a doctor. I really don't think my heart should be pounding this much and having trouble breathing is pretty serious. I am so tense I think my neck will snap off if my stomach doesn't burn me from the inside out. I'm going to Google "anxiety attacks" and see what the almighty internet has to say...
Yep, that sounds about right. Can anyone score me some Valium?
