Anxiety

Why do I have so much anxiety? Up until two weeks ago, I was adamant about not finding out the baby's sex. Then, both my sister in law and a good friend have their ultrasounds and find out their babies' sex. Very happy for them and most importantly, the babies are healthy and well. So now I'm overwhelmed with heart pounding, blood pressure rocketing anxiety about our ultrasound which is in exactly 48 hours. I'm anxious, nervous, scared, etc. Already feeling the emotions of finding out the sex (which we're now going to do because I couldn't live for 4.5 months like this). If it's a girl, I'll be ecstatic and overwhelmed. If it's a boy, I'll be ecstatic and overwhelmed.
James just came up to me and basically told me to turn the computer off. I'll post more later. If I'm not passed out from lack of sleep from ANXIETY.
