Reality check

So we are making progress with the moving plans...sold our house, it passed the inspection and now we just move forward to closing on May 14th. We made an offer on a house we love, they accepted it...it was inspected and all is good...now we move forward with closing on the same day May 14th so that we aren't homeless. I haven't started packing yet. I should but I can't seem to get myself geared up to do it. I know that suddenly I am going to be panicked because moving day will be like 10 days away and I will have JUST started packing...cause that's pretty much how I roll...
I am excited to move. I am really really excited about having a garage. Having two bathrooms. Having a huge yard for the girls. Having space for an actual toy room. Everything about the move is a win win situation for us. I honestly can't wait.
So my question is: Why do I get a lump in my throat everytime I take the girls to one of "our parks" the "blue or brown" parks? They are parks! We will have parks to go to near our new house...and we will have a yard that is basically A PARK! Tonight we went to the blue park and I couldn't help but feel sad....that has been our routine...it's what we do...I watched Katey learn how to navigate the jungle gym and go down the slides and finally show me how she can pump her own legs and swing! I guess it just feels strangely sad to know that this won't be in our regular routine anymore...
So the reality of moving is settling in-I am sure this won't be the first time this happens and I will definately shed some tears when we empty the house and walk away for the last time...it makes my throat tighten up just typing this. I guess the saying is true-Home is where the heart is...and for the last 7 years my heart has been here:)
