What Are Tears Of Frustration?

I think the tears come because yes, your subconscious knows you can do it but your brain refuses to listen. Its like someone with an idea and someone freakin out. Your brain is trying to understand things it cannot comprehend so it is getting more and more frazzled until you just break down into tears. But all the while your subconscious is like calm downnn but of course the brain isnt listening, its busy! so when you finally just take a breather and chill out your brain is like, o! i have an idea!
