My mum has a sunflower lanyard - she has PTSD and wearing the mask causes her to extremely anxious/pass out . Safer all round with the lanyard !
So far no nasty comments or questions - we’ve used buses, taxi, been to New Look, Iceland, Superdrug and Boots and had no problem at all .
She will be continuing to avoid longer contact though so pub, cafes, restaurants, swimming pool, hotels, theatres, museums, cinema, all out of the question I think . And probably long distance travel too ...
Very, very difficult but certainly no ones been rude to us, no abuse thankfully, most people have been very kind or just haven’t even noticed . She does wear the lanyard constantly and it does have a badge on it saying, I’m disabled and can’t wear a mask... not hugely discreet but neither were the results of her trying to wear a mask instead !!
