for me it would probably be assassination classroom. I watched it in year 9, and i was at a very low point in my life. It made me realise the importance of having a parental figure in your life, and it doesn’t necessarily have to be a teacher like in the anime. Ended up moving schools and i have never felt happier, my teachers are amazing.
i hate the students though lmao can’t wait to get out of here.
Actually very similar situation but also different, in Year 9 I was also having quite a terrible time (well mostly within school) and since I was rather depressed at the time, I would use anime as an escape from reality to clear my head and have a bit of a laugh.
I moved schools after Year 9 and then again after Year 10 (school I was in for 1 year in Year 10 was not mainstream and only really went there because other schools were out of area at the time). Same here, teachers aren't tooooo bad, students are ok although I still feel isolated at the school as a result of being a reasonably new student as opposed to those who were there since Year 7.
For 5cm per second though, it's only really something that I would be able to relate to within circumstances, since its all about dealing with unexpected situations which separate human connection. Although what it has taught me is that although there will be situations which are unexpected or unfortunate, over time you just have to try and find the will to move on and conform to reality, as it hurts even more to dwell on the past. And sure whilst these things should come naturally to anyone despite whether they watch anime or not, I feel as if anime has a way of showing life lessons like this in a very unique way.
