I think posting here is one way the members do cope with such "terrible" days.

Don't harm yourself for what occurred today. You don't deserve that on top of everything else. I'm glad you came here to share you day with us. I'm sorry to hear it was so tough.

Maybe if you get time you can think about what about that long session is giving you so much turmoil in mind? Please try to eat a little something. I hope you have a good night's sleep and don't drag any of this angst into tomorrow.
