Irene, you are advertising in the wrong area, I think.
In my answer, to what I assumed was your question, as that's where you posted, I wrote
"I can't do this anymore. " - the sentence, then the less than natural explanation for a non-native speaker, to clarify-

Your pointer to what would be better was to exactly what I wrote.

If you comment again, you can get even more visibility form one pseudo-question. :)
I didn't mix anything up. Thanks for helping. I always assumed the main ingredient to being a good teacher was to listen really well.
Thanks for the offer.
Zoom has been getting a lot of media attention here for its security issues.
Enjoy.
:)
