How do I not let this control my every thought?

Question.
i've read on here and other sites where this A is like a drug and actually creates toxins in the brain. is she truly like an addict and has to detox before she is ever "her" again?
not asking for "us" because i truly believe that's over and can't be fixed. i'm just wondering for the long haul. she will forever be in my life as we have two children together. i can't even look her in the eye right now when we exchange our kids. i'm ashamed of her and the way she's ended up.
it's almost like one of my old best friends who got into meth. he was a family man, even got custody of his child in his divorce, and then he got hooked on crystal meth. screwed his whole life up over it and to this day i can't even stand to look at him when i see him, knowing the hell he put that little girl through. i know i would do anything to have my kids living with me and he had his chance and blew it over getting high.
anyway, i was just wondering how many of these women get over the euphoria of the OM and come back to live in the real world with the rest of us. she's done some of the stupidest things in the last couple months since this started and i just want to be able to look her in the eye and respect her enough again to say, "I hope you and the boys have a good week" and really mean it. and not walk away shaking my head at this shallow, selfish person she's become that thinks what's good for mommy is good for the boys.
