I didn't say she was suicidal, I said IF she'd had to stay indoors for the past year she probably would have been. Luckily she has kept going out for the good of her mental and physical health
So she wasn’t suicidal at all, you just predicted she ‘might’ feel that way if she didn’t keep going for walks. On one hand you describe her as being overwhelmed with an anxiety disorder, on the other you describe her as maintaining her mental and physical health with regular exercise.
To the poster who said if they heard somebody say hands face space they'd think they'd lost the plot - yes, precisely. It's extreme anxiety that is causing people to act like this. Not some inherent unpleasantness
I’m afraid it comes across as unpleasant whether motivated by anxiety or not! How are people to know she has extreme covid anxiety? They may think she’s in a bad mood or aggressive and taking it out on them with her muttering.
There have always been mental health conditions and disabilities which might cause people to behave ways which would otherwise be considered socially unacceptable. Should they all stay at home too, or just people who have been pushed to the edge by the pandemic?
I think you and your mother need to realise a lot of people have been ‘pushed to the edge’ by the pandemic and snapping at people to move out of her way in public is unacceptable. How do you know the people she mutters at don’t have a mental health condition or disability that causes them to misjudge social distancing? How do you know the people she mutters at don’t have anxiety/depression and feel panicky about leaving the house again thanks to being ticked off by a stranger for overtaking!
On one hand you say she is so anxious she won’t have the vaccine but she doesn’t seem to have addressed this anxiety or been diagnosed or treated for a mental health condition.
Different if she has no control over her behaviour due to illness eg if she had dementia or lacked capacity to understand what she is saying and why. But saying ‘hands face space’ is a very direct and rude way of telling strangers to keep away. Which may not always be possible eg if she chooses to walk on a narrow footpath or pavement alongside a busy road where people have no other way of getting past (other than stepping into traffic).
