Doctor's Appointment

I have a doctor's appointment this Friday. I guess I will have to leave a bit early from work since he's only available till 5 PM. I don't know how or when or why it's come down to this. I'm even a bit scared of going because I feel like it's re-affirming my assumptions that there is something wrong. It would be nice if a friend could come with me, but I know they still have work. I don't know any more. I just feel really tired and down.
