Hmmm... Doesn't really fit.

Some of Your Blood - Steve Rasnic Tem, Theodore Sturgeon

 

I had this marked for Classic Horror, but it's not really a horror story.

Unless you count childhood neglect/abuse as horror.

 

It's an account of a, surprisingly stable after he told his story from childhood to enlistment, man who ends up in a mental illness facility because of a 2 line letter he wrote to his girl and punching his superior officer during a scuffle with the MPs.

 

It reminded me of reading When Rabbit Howls.

Or maybe closer to I Never Promised You Rose Garden.

 

 

Since it doesn't really fit any of my squares, I'm not going to slot this for now.
