I'm going to say, yes, it is normal to feel that way. I say this because I am in the same exact position as yourself. I only have two more days of a short 5 week orientationa and I'm trying really hard not to let the stress of being alone eat me alive. I feel school did not prepare me at all for work. I'm just going to try and be positive and learn as I go. It's a very uneasy feeling to not know the ropes and what to do, but this is how the process works. Good luck to you! I hope it gets better for the both of us. Keep your head up!
