I am excited to get into school for the nursing program so that I can quit my job and go to school full time. I think that is my main motivation. I just want out of my current job. I don't know what to do but every time I get into this office and sit in this cubicle, I feel the need to go home and drink heavily. I am not pleased with this working environment.
That said, what makes me think that I would be a good nurse? If I have this many questioning thoughts about it? Why do I drive myself crazy??? I need help. SEVERE HELP!
Geez, it's only 3:30...I need to get out of here.
