to be or not to be?

You know, its just 2 days since I started my attachment. I began to think whether this is really what I want. I keep on re-assuring myself :

Yes, this is what I want! Its not even the first week. Give yourself time.

I dont know if this re-assurance is going to last me. Suddenly, I miss school. I rather go back to school & I think I make a great nurse-educator rather than a nurse nurse.

Today, I handle a few serious cases (I cant revealed much as I can be sued!) I was in a state of pa-ra-no-ya : paranoid la. I think I wash my hands more than 10 times and once I got home, I shower quickly!

:(

Am I the one feeling this way?
