Orange, you have my total empathy! DD has been horrible, truly awful for weeks, even giving DH the finger this week, “because he’s annoying me”! 
While I understand they’re teenagers and dealing with all kinds of stresses and pressures, it’s still exhausting to deal with and VERY difficult to like them when they are being so vile and difficult.
Exams here from Monday for both DD and DS, so the atmosphere is explosive here, not helped by DH and myself feeling completely wrung out by life generally (DH still not able to work properly, so we’re still living in a financial black hole).
Thank god I found yoga again during lockdown
