I hadn't heard of this before, but after reading this, I looked it up, and this post, combined with this review, is definitely going to be enough to get me to give it a try:

This was the most emotional and psychiatric damage I have ever taken reading anything. How dare you write such vivid settings and characters that make you fall in love with people that DO NOT EVEN EXIST. I would wait 8 years. I would wait 80 years! If I only I had the hope of ever being pulled back into the world you MONSTERS have created just once more, through an entire arc.

This is so fucked up and stupid and I feel dumb for even admitting how it’s making me feel, but I just have to because otherwise I’m going to overflow. 😖

Try not to beat yourself up about it too much, it isn't dumb, it just isn't rational. But that's OK, we aren't beings of pure rationality, no shame in that. Maybe having a physical representation of those characters around could help?
