Leave me alone

Everyone else can get grumpy, but I can't.  If I get grumpy then I get berated by "What's wrong with you?" "Are you okay?" "Do you need to go back to the hospital?"  I'M JUST IN A BAD MOOD, GOD DAMN IT!!!  And all you're doing is making it worse.  Not to mention the constant "How you doin?" "Everything okay?" I already get.  Why can't I be left alone?  Why do they have to incessantly bother me?  I have problems and I'm trying to deal with them.  I'm not telling them to you.  So shut up and go away.
