Questions about example sentences with, and the definition and usage of "Reasonates"

A: Resonate is the word here. It is spelled incorrectly in your quote.

Resonate in this case means to be something you agree with in a kind of emotional way. For example, if you just went through a bad breakup with somebody, and then you find a sad song to listen to that has words about how sad you feel after a breakup, you could say that the song "resonates with you."

So the above sentence would mean something like "I can really connect with how that makes me feel, and I now feel that I have a better understanding what my life is about."

I hope this helps.
