Speaking as someone who's personally had reason to be cared for by mental health nurses as an inpatient several times, and longer term, for bipolar, I'm incredibly grateful to your fellow professionals.
It takes a very special, highly-skilled person who has personal qualities and great sensitivity, quite apart from the practical side.
(I would imagine a learning disability nurse absolutely shares those characteristics, too, @hula008 )
On a couple of occasions, friends have literally been stopped from taking their own lives only by the amazing support from MH nurses.
One of those friends got stuck with a notoriously pompous idiot of a consultant (not the norm, luckily) and was treated pretty shoddily and dismissively: their key MH nurse advocated and bent over backwards to press for better medication management.
Anyone denigrating the work you all achieve, often up against a shockingly under-resourced system, can bloody do one.
And as PPs have stated, the fallout from the Covid-19 crisis will be immense. Perhaps those that don't appreciate you now will then have the grace to admit they were ignorant as to what's entailed?
Stay safe, and thank you from me.
