not sure but it might be some 2000's horror anime or something. It doesn't look like junji's "art"....well that might narrow it down. I will just camp here now that it has got my attention......
I am surprised you don't know Neon Genesis Evangelion. I recommend watching it if you like depressing content. Totally relatable... if you're someone with parent issues.
I also didn't watch many good animes . Too lazy to watch old good anime. I only started watching anime from 2016(Not much exposure in my country, also due to lack of tv channels and and and internet speed and connectivity)
That was neon genesis...damn it's been a while (more than 10 years lol) since I saw that. I don't remember much. Honestly since none of the shows nowadays are great I might go back and watch the 'classics'.
