Did I Make the Right Choice?

I would not describe myself as weak, ever. I have never quit anything in my life, but I am so very close to doing just that. I have been challenged by so much in the past. I have undergone brain surgery, been forced to give up more than half of the foods I eat regularly, and I have survived endless hours of twisting and turning my body in ways that physically should not be allowed. But this, this African life that I chose, this Namibian adventure that I was so sure that God called me to, I do not feel I can do anymore. I have been stripped down, I feel raw, and for once I feel severely weak, as if I made the wrong decision to move. I am upset and feel used more than I am enjoying my stay, and because of that, I am wondering if a whole year of living like this is worth it. It would be easy for me to pack my bags and head home after my parents' trip. I could say goodbye and go home to start a new chapter, but the problem is, it's never that easy to make the decision to actually go. As I said, I am awful at quitting things, but is my unhappiness here worth it? 

Overall, I am frustrated and irritated. I do not like that I never know what is going on. I do not enjoy people talking about me, but not realizing that my name is clearly translatable. I miss my privacy and the ability to have control of my life. And lastly, I wish people would have explained things to me from the very start instead of making me feel small and stupid this late in the game. I am unsure what to do, unsure where I should go from here. I am afraid to disappoint myself, the people back home, the people here, and most importantly God.
