My experience in LTC

Okay, so I am sure most of this is in my head but here it goes.

I have been working as a new RN in LTC for 4 months now. I work overnights as the supervisor for both floors. It was stressful at first but now I am familiarized with most tasks and feel comfortable. The only time I don't is when I really want a second opinion on a acute situation and the only two nurses working are LPNS that are newly graduated as well. This can sometimes be stressful, but I feel as though I've always done the right thing. MDs known to be rude are never to me even when I call them at 4am, meaning I must be making appropriate calls/decisions. So far I have barely gotten any feedback! I began to pick up on 3-11 very quickly, so I could receive feedback and ask more questions since there is more than one RN on during evening shifts. I was never trained on the med pass, but I quickly began to pick up on 3-11 med pass and be efficient. I also do the change overs at night and do not make mistakes. I am very young (22) and sometimes feel as though I am out of the loop. I feel like all the other RNS communicate with each other and I am just "there". I wish I felt more included sometimes, but I feel as though they don't value my opinion? They just appreciate that I pick up shifts and don't make mistakes? The only thing I've been told is my charting is excellent, but I want more! I want constructive criticism; I wanna be told what I could improve! Sometimes I feel as though I'm just there for my RN so when LPN supervisors make decisions I can sign the paperwork. I don't know if they find me a valuable member of the team or just a filler for shifts. I do everything right but I just feel like I could be doing more. When I give report to the one morning RN I feel like sometimes she looks at me like im stupid, but I don't have much to tell her since night shift can be pretty dull. Does anybody else feel like they aren't as involved as they should be? what can I do different?
