I want to wear a mask. It is the right thing to do. I've worn masks since we were advised to do so. But I've started struggling with them.
My asthma is not well controlled at the moment and I've gone from being fine for up to 1.5 hours in a mask, to starting to feel uncomfortable within minutes of wearing one. Yet I can still cope for an hour if I take my inhaler beforehand - it's just uncomfortable. But because the asthma is problematic right now, I feel uncomfortable many times a day anyway. So wearing a mask won't necessarily make my day any worse than it would have been without the mask.
Sure, I can be exempt from wearing a mask. But I want to wear a mask. I work in education, so am very exposed - I should wear a mask to protect others from me. And I really, really, do not want to have to keep justifying myself. Especially if I cough - which I'm likely to, of course, as I have asthma.
So I'm sitting here in the carpark worrying about doing my shopping wearing a mask, and worrying about doing my shopping not wearing a mask!
