Makenzie,
Posted on your Introductions message, so glad you found your way here.
Take it as a positive that your scan was clear, we all have so few plusses that to hear about one for another member is a boost to us all.
I AM sorry to hear your TN is affecting your ability to eat, and especially your mood. My TN covers the whole of the left side of my head and face, doesn't affect my eating but makes me drool at inopportune moments.
Things like this, the constant pain, will lead to Depression and you are clearly having problems there. Have you spoken to your GP about this? It is a serious matter which makes everything else worse. I know you turn to God, but you can also find support here. The places for this are, Sanctuary for Spiritual Support and Depression Forums.
They are not a substitute for professional care, but the members are going through the same things and understand.

Dave.
