So the generic "Feel" is like a severe emotion or feeling one gets to a certain something.
Feels can connect one to an anime character with similar reactions to an event, or merely they have those "Sympathetic Feels" towards them. However, like junk food, too much is bad for you.
Mmhmm. Let's use Kyou, Koi Ko Hajimemasu as an example. A slice of life manga about a girl who goes to high school, meets this douche, ends up cutting his hair in an arguement-because everyone carries scissors
(That is not how we carry scissors, Sachiko)-and it goes on to explain how they learn to tolerate each other. The whole progress goes like this:
-Not really interested.
-Want to punch some of the characters
-Relief that everything is okay
-STAB IN THE FEELS
-Relief and happiness
-SADNESS
-Happiness
-DEPRESSION
-Overjoyed
And re-wind and start from number two. See the drastic change between some of the stages? That's the "feel slope". Kind of like an accurate measurement of the change between mood shifts. When it is that drastic, it's just too much.
Another example (for me at least) is Clannad. I wanted to avoid it as much as possible (didn't work out; it's on my to-watch-list). So, I read on the wiki to see how it ended.
THE WIKI MADE ME CRY.
I WAS CRYING FOR THIRTY MINUTES.
I was stuck in a mini-depression state for the rest of the night.

So yes, when it is that severe, IT ISN'T HEALTHY. I should just be thankful that horror has affected me to the point where my "emo-corner" is the bed. Too scared of corners...
*MAYBE A SPOILER?? I GUESS YOU WOULD NEED TO KNOW WHAT'S GOIN' ON*
That's the end of my rant...All the "feels" have left, so I feel better. *CUE COMEDIC DRUM NOISE*
Close enough. So, have you experienced a feel overload?
