Awful

My guitar playing at practice tonight was probably the worst it’s ever been when other people were in the room.  I’m stunned they didn’t sack me on the spot.  My hands hurt so much I just couldn’t make them do what I needed them to do.  It was just awful.  What if this never goes away?  What if it gets worse?  What if I can’t play anymore?  When does it get so bad I have to see a doctor, and what if the doctor tells me I’m done for good?  I am literally scared.
