Waifus aren’t real. I know it hurts but you can’t let it get to the point you’re at. You have to accept that you are infatuated with this character, and that she isn’t real. I know, very well, how difficult that is sometimes.

There are different ways to cope. Pretending to make pancakes for her sounds like it intensified those feelings, instead of dealing with them. If your computer isn’t taken away, try porn. Try writing. Try thinking of other characters/people you are attracted to. Try making pancakes for family or friends so that you do have someone to share them with. After whatever you try, assess if you feel better or worse.

I’m not a psychologist, take any advice with a grain of salt, these are just some things that work for me.
