Blank and Numb

My head aches.  Really, what the hell?  Again, despite waking up late, I'm exhausted and absolutely dreading working tomorrow.  I'm having super high anxiety for no reason at all.  Dave and I tried going to Jordan's for some ice cream but I was super anxious and afraid for no reason at all.  I just felt myself close up and shut down.  I don't know what's wrong with me.  I'm desperately hoping that this is just a slump because I feel like I've taken a huge step backward in my progress.   Seriously, I just want to go back to bed and sleep forever but nothing has happened.  Nothing changed.  So what am I doing back in the space.  At first I thought I was just being lazy, then I realized that I was feeling under the weather, but now I feel physically better but mentally.   My mind is just blank and too numb.  I need to get over this.
