I'm sorry about your mothers illness and passing. I bet you were able to help her much better with the CNA class under your belt. What a blessing.
I'm in Michigan. I would make sure you get out the pamplet that we received and practice on anyone you can. Schedule that time in with someone who'll let you practice on them. I think it is normal for all of us to be nervous, but you need to build confidence. I believe the way you do that is to learn the skills really well. If you don't have anyone to practice on, then pretend. Say the steps out loud as your are doing them. Good luck! You'll do fine if you prepare yourself.
