Hi Karl
Hope your hand's feeling a bit better today - if you're thinking of going to A&E, bear in mind it's a bank holiday so they won't be doing 'routine' X-rays!! Just to help you smile maybe, I share your physical pain - I stubbed my two littlest toes on my right foot last night and now I'm hobbling! I think something may be fractured but there's not much they can do for toes.
Haven't got any better advice to offer than what's already been posted - you did really well not to punch her, I think I would have How insulting and insensitive of her to suggest that you should be sectioned! You're correct - it just proves her ignorance.
(((hugs)))
