Anime withdrawal, it happens. What its official community known name isn’t known to me. I do call it a Anime Withdrawal. There is also Anime fever for short term obsessions.
Well, when we like something a lot we tend to dwell in it deep and try to explore every corner of it right? We dwell so much in a single area of our liking that we tend to get “withdrawal” symptoms  when we’re done with the certain something. It’s something were you can’t keep your mind off such an area for an extended period of time. I have felt the symptoms of Anime Withdrawal were I wanted to watch anime but couldn’t due to traveling, cultural, “real-life situations” and various other scenarios. All I could do was talk and think about Anime (even in non-anime areas), or just adapt to the new scenario/location.
Disclaimer: Everything I said is generalized or simplified so it can be listed with ease. Some things may not even be accurate because we each experience these symptoms differently and some things maybe confused or forgotten. Sources? Myself, other people, various sites and you guys/gals. I listed everything with what I experienced.
