This forum at least claims that it is also for "pre-students"--people considering becoming a student of nursing. If other participants here have similar views to you of not thinking the forum should include members who are trying to decide whether to enter nursing, then perhaps this is still the wrong forum for me regardless of what it says on the tin. But I haven't had a chance yet to assess what other members here think on the subject, so I may give it a few more days before deciding whether to keep my account.
Obviously I won't be able to contribute much here about nursing beyond asking questions, but it's possible I might have questions that other potential nurses would want to see answered.
Experience and knowledge are two separate things. Sometimes they are correlated. Sometimes they are anti-correlated. It depends on the efficacy of the training, the range of experience, the appropriateness of insights or strategies learned from those experiences, and various other factors. This is such a universal feature for so many skills/knowledge-based careers that I feel it must also be true for nursing, and it is consistent with what I've experienced as both a patient and as a health researcher.
I am sorry people have conveyed such messages to you or have made you feel unvalued. That was wrong of them. Hitting back by trying to make new nurses feel less valued is probably not the most productive coping strategy, but I can understand that it comes from a place of pain.
I hope your work environment becomes more supportive of you. Every worker who tries their best deserves to be supported and valued for their work.
