Anxiety through the roof!?!

Iam 38 weeks and 2 days today. Woke up feeling so anxious and frazzled. I had 2 appts that I just cancelled because I feel the overwhelming need to just drop my kids off at school and my fiancé at work and get home and stay home. All I want to do is clean up the house, take a warm bath, crawl back into bed under the covers and stay there in my safe familiar bed for as long as I can. Ugh what is going on, I feel SO weird and just off and I can't stand it. Literally trying to hold back tears as I type this.
