OP, it is likely the hospital or unit your are in and not personal to you given how little time you have been on the unit and that you have significant nursing/ hospital experience. There are some hospitals that are incredibly toxic and the culture is to be rude to newcomers due to frustrations in the work environment, "it was done to me", or just the personalities on the unit leave a lot of be desired. The last hospital I worked in was like this (and I could not believe a place like this existed until I saw it myself). If your hospital has a significant amount of derm on the inpatient side and engaging with staff still proves to be difficult over time, you may be able to connect with the WOCNs (if your hospital has them) on certain cases to help ensure the care plan is carried out if needed.
The good part is that you are out of there in 4 years and I imagine a significant portion of your rotations are outpatient in derm. Just remain professional, do not engage, and focus on learning and patient care on the in patient side. You have shown yourself to be respectful and professional in your posts here and I have no doubt you will be successful. Best of luck in your future endeavors and congratulations on starting this great new chapter!
