Called Hospital

So on Friday I called the Hospital and asked to volunteer at the help desk and they asked for a 6 month commitment and were very interested. So I made an appointment for Monday at 1:00 pm. Tomorrow. I am a little nervous and excited at the same time. Its taking that next step into the human race.....I hope I can sleep tonight. The good news is before the appointment I see my counselor, then the interview and lastly a massage. After 9 years at one job and how terribly they hurt me because they needed to get rid of their highest paid employee. It still killed my self confidence. Then the let down when I volunteered to deliver meals to the elderly and rejectected because I was honest about my PTSD.They thought I was awesome til then. This time I can just say that I have been lucky to not have to work for the last year and  I am a little bored so this is something I would like to do. What do you think? Any other ideas on ways to say it without lt being a lie, because thats not me.
