Oh my, yes this is a lot going on, makes sense you are tense. Are you feeling any better yet? Try to continue to get your good sleep.
I was very tense today. Decided to try some cannabis... I then got a burst of focus and hand washed 2 cars, and did a bunch of yard work outside. The outside work was really good for me, I can't believe I got all that done. I wish I could be efficient in getting laundry and housework done. I'm happier outside. It was beautiful weather today.
There isn't much you can do to change the outcome of these things that are out of your hands. You're preparing emotionally, that's really good, and will handle it as best you come. I really hope you get the job.
