(((googley))) I'm so sorry you are feeling this way. I was feeling this way last week and right up until last night.
Journaling my thoughts and feelings while I was like this was a big help. I also had to remember how much progress I have made and remember you have made lots of progress, too. Breathe, and focus on your session tonight. I am sending you some positive and Happy vibes. I'm with you and I totally understand.
