Welcome!! Congrats on your date! That will come up real fast on you!!
The way you are feeling is normal, I was feeling the same way when my surgery was sched about a month out. Now mine is a few days away and I am calm and ready...I am sure the nerves will creep back up!
This is the best site I have found by far for honest advice, inspiration, and just a great support system to work with what you already have!!
