I think the problem with Sakura right now and why it's so hard for her to let go of her love for Sasuke is that she so desperately wants that fairy -tale love that Sasuke pointed out (and that she actually mentioned in chp3 before the NS bench scene). Like, I think thanks to that moment and the fact that Sasuke actually thanked her after her first confession before knocking out so she wouldn't cry for help, she probably still believes that that Sasuke is still somewhat there and was trying to reach out to him because it was the only thing she could do. And it's not so much that Kakashi's supporting them being romantically involved with each other but he said what he did because Sasuke's actions were incredibly harsh considering Sakura's doing all of this despite how much bad he's done. He's repaying her kindness with a cruel act. She's just doing her best to save him the only way she can, and Kakashi's upset because Sasuke just can't see it that way.
Sakura doesn't need a psychiatrist...she just needs to let go of her childish view of love-this view that she has to do big things for the person that she loves and if she can't then she's not worthy.
Or, she needs to at least realize that Sasuke is not who she thinks he is. He doesn't care for her the way she thought he did (that was Naruto). And I think, this moment is going to make this happen, along with Naruto's confession and, possibly, Sasuke apologizing for his treatment of her and explaining to her that while he may see her as his comrade it's no more than that.
