Hello,
I don't know what kind of tolerance level you have for something like this, so I wouldn't be able to tell you what to do. It could very well be too much if you are not prepared. But on the flip-side, it could also show you something else entirely.
Some scenes might feel too real, mostly because a bunch of them actually happened to me, but that shouldn't be a deterrent really. More like...something that gives the novel grit.
I'd say give it a shot, but be aware that there is a reason for the content warning. Things get very real, very fast starting on page 1.
Best regards,
-H.M.
