Need Some Advice and Truth

I need a little bit of advice on how to work with this career. I joined the career of nursing, currently a CNA right now, to continue in the field to really help people that are in need. I am happy for the kind of work that I am currently performing, because I see that people are getting the help and am glad to be a part of it.

Before I go any further, first I would like to say, that I understand that we all need to take care of ourselves and our own things/sets. So..I generally do so and ask for help now fewer and fewer..Currently I work in a large assisted living care retirement center. I have been there for six months, and this is my first CNA job. Since this is my first CNA job, I am bound to make mistakes and I have, except nothing deadly or damaging. However I am getting some issues with some of the other staff.

1) From the start most of them seem to look at me like a foreigner. I try to smile as best as I can, but it comes to no use. I would talk to them sometimes, to try to built a professional repour but it does not work. I would occasionally ask them for help, but they would say, "yes, what" and would look away, or just ignore. Frankly they also did not seem to want to train me in the running of the place.

2) Sometimes to half of the time I just plain get yelled at, because, I either ask for help, or don't ask for help...It was very confusing to me.. In some cases, again ignored.

3) I would make a mistake, I never knew about, I get yelled at by the immediate supervisor.

This eventually caught up to me not once, not twice, but three or four times in which I either told the head nurse, about being yelled at, and she eventually told the Nursing Supervisor, or I went to the nursing supervisor myself and told her myself. It started coming to the point, where the nursing supervisor is so irritated about this and cannot do anything about it anymore, which I don't blame her, because I would be too. It is also, letting me down and down and has an effect on my job performance. I tried to keep smiling and being positive, but it is slowing down. The Nursing Supervisor did tell the staff that we all work as a team. That sort of half way happened. But anyway...

I did not tell her that part. The reason why I did not tell her that part, because she was already so irritated anyway. Eventually I went up and told my immediate supervisor, to please stop yelling at me, I do not like it. She went to tell the Nursing Supervisor, and I got cut a shift. I also got cut a shift for making mistakes I did not know about, even though I told the Nursing Supervisor.

The advice I am asking is:

1) Is this normal?

2) How can I work with this? I left Education because the parents were rude and in some cases abusive. I have been told in the past, "grow thick skin"! But how does one do that. How do I work towards growing thick skin? During my upbringing I was yelled and even smacked at, for not understanding academics. I never grew thick skin.

I understand if it is an angry resident. I also understand if staff are stressed out, but why take it out on others. I don't.. I am not trying to criticize, but rather am asking for advice on this. I really want to continue helping others and become an R.N. I am in my mid to late 30's and therefore do not really want to do another career change. any help would be necessary.. Thanks.

P.S. It is already bad enough, that I work alone most of the time at this place...
