EML, never worry about whining here. It's probably the one place we all have where that's perfectly ok.

You're obviously a smart guy and you've done your homework. You're doing all the things you're supposed to do. In fact, you're so smart that you even know the ultimate outcome to all of this, which is that the cliches will prove true and time will heal your wounds. But knowing how all of this works doesn't ease the pain you're in right now and you have my complete sympathy.

My only advice is to suffer through as best you can by focusing on tiny things that make you a little bit happy. Or at least, a little bit distracted. While it's true, you do need to feel all of this in order to process it, you're doing therapy and all that so time has been sufficiently allocated to inner turmoil. The rest of the time I think is best spent treating yourself to a few guilty pleasures to get you through. I think this is why women eat lots of ice cream after a breakup.

I hope things get sorted out with your ex and I hope you feel better soon.
