Well it's good that you think that this is anxiety related, it's some relief. I tried to calculate the G force, and I think it was probably under 5G, does that sound right?

As for treating the anxiety, I'm trying to do exercise, which ironically enough often puts me in situations that create more worry like this.

I guess at the end of the day I'm just an anxious person in general. But more specifically, I'm in a challenging program in university, and I'm worried that even a small impact on my cognition will cause me to fail out, as unreasonable as it sounds.
