Feeling sick over hyperfixation

Hey guys, i wanted to ask about something that I've never experienced before.

I have had hyperfixations in the past, but nothing to this degree. I started hyperfixating over twilight last year, it started off as rewatching the DVDS over and over again, until I got bored of rewatching them, and I eventually dropped it.

I got twilight books for my birthday and Christmas. I didn't touch them until two weeks ago, and finished the first three books within a week, along with 300 pages of the fourth (1,400 pages, at least). I prioritised it over school work, over a lot of things I shouldn't have.

Now, I can't watch or see media relating to it, because it makes me feel insanely nauseous and makes me so depressed. I got insanely depressed the first time, because I was close to finishing the book series and I wouldn't be able to get the feeling back of reading them for the first time, so I haven't finished reading the fourth book.

Has anyone else experienced this??
