I'm sad

I'm sad because my head hurts and I'm so tired of it. I don't want to keep trying to find a cure for it. I want to quit. I want to stop being in pain. I want to stop spending money on this. I want to live a quiet and happy life, well maybe not quiet. I want my old life back where we did fun things and went places and explored and I never worried about pain. I don't deserve this. I worked so hard to be healthy and this is what I got for it?

I know no one deserves pain and I know I'm not handling it graciously. I still don't understand the lesson 5.5 years later. Why did this happen to me? What purpose did it serve? What lesson is there in it? What do I take away from this experience? How is it helping others? How does it work through me to give to others?

I don't know where to go from here and I have no one to talk to about it. I feel so alone.
