Feels like I am pushing

Ok so I went to work yesterday evening.  I got myself out of the house and went in.  I had not even fully gotten into the building when I felt like I was going to have a panic attack or breakdown or something.  I am pushing myself only because I am needing the money.  It is like pure torcher.  My mother said it will do you good to get back to work but she doesn't understand where I am at in my head.  I stayed for the whole shift and came home.  I had to go back in for a while during the night to deal with an issue with an employee.  I don't believe I should even be behind the wheel right now much less dealing with employees.  I am extremely tired today from just the effort of pushing through yesterday.  I feel extremely aggitated or on edge today.  I don't know what to do because I feel like I HAVE to go to work to support myself and my kid but I feel like it is also 'killing' me to do it.  That is tearing me apart.  If things get worse tonight I think I will just take myself to the hospital. I guess I am just ranting here.  Not sure what to do from now.
