I completely understand what you are going through. However, if you want to become a nurse badly, then you should hang in there, it will be rewarding and well worth it at the end. As far as being criticized, maybe your professor is trying reverse psychology on you. Some people get motivated when they get criticize because, thats what drives them to do better. So dont take it negatively, take that criticism and turn it into something postive. Then next thing you know, you learn from your mistake and will do better the next time around. But dont let other discourage you or tell you otherwise. You can do anything as long as you set your mind to it, you have made it this far and I bet you work really hard to get where you are at. Dont let that just slip away. I know life seems to be on pause at the moment, but once you work hard later on you can play hard
. I wish you the best of luck.
