Echoes even if you do get mad in session, that wouldn't count as "blowing the session." It would count as being brave and expressing your feelings to her.

Keep in mind that you have good news to tell her. Remind her that no matter how you feel, the both of you will share in your good news-- then you can get mad

Since she feels farther away when you push her out of your mind, what would happen if you thought about a connecting moment you had with her? I know that thinking about her will make you miss her, but you are going to miss her no matter what! Maybe it is okay to bring her a little closer to you instead.
