>My psychologist recommended that I watch anime to relax
Your psychologist sounds unorthodox at best, retarded at worst. And they probably have shit taste anyway
>I like to immerse myself in things so I can forget everything but finding something interesting enough that my mind doesn't wander is difficult. It seems like manga are more suited for keeping my attention for the long term, especially with all of the episodic stuff I see here.
>So what are some series/movies that you've found yourself really lost in?
Look mang, I like jap toons and comics, I do. I've had times where I was in a difficult spot, and mango and toons did provide some relief. But going out for some walk or exercise, would probably be better. You don't want to get lost for too long in escapism.
If you really still want some recommendations. I found reading Yotsuba to be pretty comfy. Good luck amigo.
