My body wants to stay sick

I’m so frustrated with my malfunctioning body.  It’s like a car that sits up on blocks, year after year, being tinkered with on weekends but never quite getting to a usable state.  I can’t get done the things I want to do, because I feel so lousy I can’t even think straight.  This is crazy.  It’s going nowhere and I’m so out of it I barely even notice.  I mean, what’s the point of a life where you’re not even conscious enough to process what’s going on, or change course? 

It doesn’t even have a simple clear explanation.  Today I felt ravenous and weak with hunger all day, no matter what I ate or how much.  I couldn’t think clear enough to do anything but resist the urge to gorge myself.  I certainly didn’t have the physical strength to do anything.  Why?  I haven’t the faintest idea.  I’m eating healthy food in normal amounts as per dietician’s recommendations.  It’s almost as though I start to make progress on one health problem, and my body just makes up a new illness, out of thin air. 

I just don’t get what’s going on.  What’s the purpose of all this?
