Finally, on this essay (sorry), please don’t tell someone you hate them, especially someone you don’t know, or blame them for breaking you: they didn’t. You didn’t have to read the comics. I suspect that you were struggling anyway and that the comic acted as a trigger. That’s not the author’s fault. It probably would’ve happened sooner or later anyway, and sometimes, having a good cry is cathartic and realising that you aren’t happy and need some help is the start of the journey to being content and well. So I think you owe an apology.
Beyond that, I hope you get the help that you need and go on to have happiness and success in whatever you end up doing, whether it be running a pet shop or changing the world, but do start the process and ask for that help.
