It’s bad enough…, but…
as well as one big original problem, now there is an extra problem on top of it
It’s bad enough that my parents are making me go to English classes, but now they want me to learn French too.
It’s bad enough that she rejected me, but now she’s dating my best friend. What a kick in the teeth.
It’s bad enough that I have to work at the weekend, but to not receive any overtime pay is insulting.
