I've heard of and thought of a few awful scenarios while in lockdown ...
1) Being a single mother of three small kids living in a high rise flat
2) Being told you have less than six months to live - not sure how much less
3) Living with your violently abusive partner / children
4) Being severely claustrophobic
5) Having an operation cancelled because of CV-19 which means that, if you catch CV-19, you're less likely to survive it
6) Having a loved one die in intensive care without you being there, and only a few "allowed" to their funeral
