Confused & don't know what to do

Usually, yes. Schools prefer that you are completely ready to commit. If you start and 1/2 way thru you just can't do it (for some reason or another) They can no longer put anyone else in there. This is not the kind of schooling that you can take one semester at a time. If you do this, it is ALL the WAY. Otherwise, you have taken a place that someone else's dream had to be put on hold. I saw this in my own program. It made very bad feelings toward that person from the rest of the group. She lost our respect.

How about this... remember how it felt your first days in the MICU? Were you unsure of how to care for your patients? Want to leave and never come back? Everyone feels this when starting something new. Totally normal. I just started in the ICU and I feel this all the time! I've heard it only gets better, and it will be the same for you. Go ahead and pursue your dreams.
