Even if it is, that's okay. Personally I hope it has empowered the OP to take self-preserving measures in whatever healthy form may be appropriate.
Whatever you believe you're re-channeling, it needs to come in the form of solidarity.
You as a caring person may wish that you could magically provide whatever nurses ask for. Your superiors, on the other hand, make plans that, at best, do not take nurses' concerns into account, and at worst are very purposeful in not providing what nurses and patients will need and in not caring whether nurses and patients will suffer. Your mistake is in believing this whole thread is about covid. It isn't. Covid is just breaking the camel's back.
If your reference to supplies refers to our PPE dilemma, organizations took purposeful steps that helped bring us to the situation in which we now find ourselves. Some are multi-billion dollar corporations that abruptly stopped caring about N95s/fit testing, etc., 5+ years ago for their own business reasons--and then proceeded to put a couple of PAPRs here and there throughout their facilities. Now any thinking person would recognize that such a plan would not leave them prepared for anything other than an extremely small-scale need for respirators. It leaves them unprepared to protect nurses, but if that is too selfish a thought for your sensibilities, keep in mind that it also left them unprepared to care for patients and to protect patients. Yet they unapologetically decided to hedge their bets and be ready to loudly proclaim their innocence and helpless PRN.
Staffing plans that keep RNs in a position unable to do justice to the role of caring for patients even on a "good" (pre-covid) day is another matter of abuse of nurses and patients that has now become abject unpreparedness for the current crisis, including the systematic poor treatment of bedside expert RNs such that their presence has been reduced.
What's done is done, you may say; we must accept the circumstances and positively move forward sacrificing ourselves and being real leaders and real nurses who are in it for the right reasons. Is there no value in choosing not to tolerate unethical foolishness and especially abuse? Our Code of Ethics (Provision 5) addresses this.
I appreciate your dedication but the case could also be made that those leaders who are willing to give everything and sacrifice everything to the call of nursing would not continually find new ways to accept mistreatment of patients and nurses. It is not unusual to hear from nursing leaders about what bedside nurses should sacrifice and how bedside will need to compromise. (Some) nursing leaders have an endless supply of inappropriate optimism about how things will turn out if only others will just sacrifice and stop complaining. Yes, I do know that leadership positions can be legitimately agonizing and that there are incredible stressors and many sleepless nights endured, but even that is not the same as going into covid rooms wearing contaminated pieces of paper because of greedy business decisions.
It also cannot continue to be about the types of sacrifice that cannot in good conscience be thought of as necessary.
This isn't about the heroics required in unforeseen circumstances; this is about others making plans for nurses to sacrifice solely because of our own history of doing so even when it is unethical and not strictly and objectively necessary. I again assert that our Code of Ethics does not call for the kind of repeated sacrifices we have been asked to make. Keep in mind that in some of these "sacrifices" we have compromised on a lot of things that have greatly affected patient care (not to mention our profession).
You are entitled to your opinion and beliefs on the matter and owe it to yourself to act in accordance with your conscience.
If you are okay with the number of good nurses who have been casually disparaged and treated as if they are the problem, that is your prerogative. Personally I believe the topic should bother you on a level other than to call someone's ethics or suitability for the profession into question.
