The new Normal

Dear Beth,
 I have been back to work for 10 days. It has been a tough 10 days. Everything seems the same, my office, my classes, the building, my colleagues.  I'm not the same.  The first day back, I had to leave early. I was so tired after just 2 hours and all I was doing was sitting. 

 I don't know how I will stand up in front of a class room.  Well, first of all, I won't be standing. That is one thing I can control. I have permission from the doctor to work only 4 hours but only the chair of the department knows that. 

To everyone else, I look normal. I don't feel normal. 

This is the new normal.
