Homesick or what?

I do not know if it is the upcoming deployment, the recent holidays, my finishing practically every class I can take and finding no new ones to take, or a combination of all of the combined but I have found myself not enjoying Germany that much lately. Don't get me wrong I love being here with Nathan, I love the traveling and trying new foods, but there is a part of me that says its been long enough, lets go back to the states. What I do not enjoy is not feeling like my life has a meaning, the continuing struggle to find a job (tired of all these promising interviews, if you say that you are interested then just hire me already, but the economy is effecting everything here as well). I miss being a nurse, I miss having a purpose everyday in getting up and going to work. How many people can say that about their jobs? I love being a nurse, there is nothing that I wouldn't give up right now to get up, put my scrubs on and go save some lives. I miss being near my family, I am not saying that I have to live in the same state, but not an ocean away. It has been a tough year on my family and especially not  being home for the holidays has been hard for me. I have a whole list of things, while little things they all add up, that annoy me right now about being here; paying to have to pee at a public location, not being able to find the foods that I wish to purchase at the commissary, the ever changing exchange rate (it is getting better the last couple of weeks), etc.
I will not lie, I am frightened about being here by myself during the deployment, I have considered going home but then I realized that by being out of Germany more than 90 days I lose my command sponsorship and visa allowing me to be here, so I will stay knowing that being with Nathan post deployment will be worth it. But perhaps I will be making a couple of visits home during the deployment, and maybe even have some visitors here, hint hint! So I am not really sure that I am homesick but more trying to find my place and purpose here in Germany.
