I’ll start by saying I have. I’m NHS staff so have been back and to at work anyway but my sisters baby was stillborn and so I broke the lockdown to visit her, she needed it and I felt it was more important at that time than the coronavirus risk. In fact her mental health team suggested it so no guilt and no regrets.
I imagine many of us have had situations where they have done the same for various reasons? Which makes me wonder how effective it really has been.
