I miss my Gramma

I think I might be experiencing a bit of homesickness, although I am not sure. Last night, I talked to my Gramma for the first time in months and I miss her. I miss a lot of people in the States, but talking to Gramma made me really want to see her. I think what is hard is I don't know when I'll see her next. I am not sure when my internship ends and my new job begins. If I am in Europe for Christmas, I'll spend Christmas in Italy with my sister and her boyfriend. So when Gramma asks me when she will see me again, I can't answer. She'll be 81 at the end of October. I don't wish I was somewhere else - I know I am in the right place. I just want to know I will get to see my Gramma in the future.
