Congratulations on your new career. I would say be focus on your goal and that is to finish nursing school and be the best nurse. People can be so rude at times and I know it bothers you but its times your going to give your best and to them its nothing. You have got to have tough skin and those nurses and cna you work with after I would have told the supervisor how you felt. I would have helped you knowing that you are new. The family is just looking out for their family member and since they are not a CNA they will never understand your point. Go to work head held high and keep your goal in mind on the hardest days because your learn so much that will help you in nursing school
