How to be successful in the zonk?

Hello everyone. I have already achieved 100+ days in this app and even sometimes I don't get what I do wrong on a word. I'm learning french and I did the breathing exercise and I'm still doing it and I have no idea about when I will finish it. I had a very little progress on this and I will really appreciate if you tell me how to zonk a session successfully or will it be good enough to just leave it for a while and comeback after some time. I have already taken like 20 days to zonk only one session.
