Im scared, Im happy, Im strange!

Its 6am, I didnt sleep well - surgery in 2 days, Monday morning and Im freaking out ( on the inside). Last night my husband and I got in a big ridiculous argument. I'm pretty sure I started it. What is the matter with me? Why am I growing increasingly aggitated? I feel like I had it all together and as the week progresses, Im losing all the calm and organization I had for this journey. I just want to cry or laugh or scream....I feel ~~~~Kathryn
