Empty House

So my family all just left for school and work and I'm at the family house all alone. It's kind of sad to think the whole family won't be together in our house again for over 2 years. I don't know why I am so sad...after all, I haven't lived here for over 4 years, but still, it's just a reminder of how long I'll be gone. I'm alternating constantly between jubilation and tears, which I'm assuming is normal, but I'm not sure how much more of my mood swings Justin will be able to take!
