I was in excruciating pain (exams, tests, qual, workloads, homework, complex ideas, real analysis, qft, integral by parts etc.). as a result of choosing physics as my major after being inspired by this image.I want to understand this picture. Which book should I read?

There are three kinds of mathematicians: platonists, formalists, and finitists. Those three are respectively basically equivalent to theist, agnostic, and atheist. Some *believe* there exists a world independent from our thought (so it's not just some shit we made up) and physical world where mathematical objects exists, others don't. Your pic is specifically something Penrose drew and can probably be found in his book "Road to Reality".

Yep, this is the answer. This drawing is on the first pages of Road to Reality.

Schizo answer :
Plato didn't invent mathematics and before him people like Thales and Pythagoras were more interested in the mathematics themselves, rather than how they worked. There are different interpretations and a change in interpretation of how mathematics work has next to no consequence on the mathematics themselves. The only thing that can be known without a doubt is that mathematics are something human beings are capable of, and in the past they explained it with mythology.
You could think it's aliens and it won't change a thing.

Math literally didn't exist in physical reality until the light of Plato's consciousness shone on it and brought its shadow to us from the realm of forms.

Essentially, it's saying that a small part of mathematics map onto all of reality (i.e everything in nature is mathematical), meanwhile, we seem to be able to understand (or atleast concieve) all of mathematics with a small part of our minds (most of our minds being occupied with other things), which in turn is only a small part of physical reality.
It's on p. 18 of Penrose's Road to reality

He's saying math is something people just dreamt up that somewhat approximates reality
