Admittedly I am in a fucking foul mood.
I have lung disease. I am also in my 40s and like to have a life (well as much as we all can at the moment). I wear a mask and am very careful to maintain social distancing etc - for myself as well as everyone else. I try to be as active as I can be (I was on the CEV/shielding list but need to balance this with keeping healthy, mind as well as body). It's only really walking in the fresh air and going into shops occasionally.
Sometimes I wheeze a bit. Unfortunately I also cough sometimes. This isn't a "dry" cough though. It sounds "chesty" and throat clearing if you know what I mean? It's worse in cold weather and I had pneumonia last year which made it worse. I know it's going to be a crap winter and I won't be out much when it gets colder.
I do understand that if people hear someone coughing it may make them nervous and I do sympathise with that, if someone moves even further away and I accidentally catch their eye and see they're worried (especially elderly people) I will usually just smile at them and say "I have lung problems, it's not coronavirus" and it's fine. But what fucks me right off is the nasty unpleasant unconcealed judging and being rudely questioned. Just this morning someone said to me (I was keeping my distance and just looking at some ham) "should you be outside?" and their tone was almost disgusted. It felt horrible.
Funnily enough this never happens when I'm with DH who is about a foot and a half taller than me and has a terrible resting bitch face. I really don't want to have to make a general announcement I don't have CV before or after I cough and like I said I don't mind explaining myself especially if someone is vulnerable like I am, but I don't want to be treated like a piece of shit who is stupid and irresponsible.
AIBU to feel if people really feel they must question me they could at least be fucking pleasant about it.
I always always keep my distance and actively avoid people. I try to cough as infrequently as possible, wear a mask (and a scarf if cold) and cough as discreetly as possible into my elbow. I have tried sucking sweets, chewing gum, carry a water bottle, have even tried not wearing a bra
