Exactly the same feeling I felt...

I was going into my final semester of school, needing to finish my thesis, apply to grad schools, taking another class on top of that, and working about 35 hours per week. What I realized at the beginning of August was that I wasn't going to have the mental willpower to get it all done without starting HRT because that voice telling me to start HRT would drown out my concentration. Admittedly, I have no concentration as it is.

I weighed the benefits of HRT with the possibility that cognitive changes (such as emotions) might also hinder my efforts, but it turns out that being on HRT was what I needed to calm that raging voice and finish my work.
At the end of the semester I got confirmation that my mental calm was pretty much a placebo effect: I had no body changes and my T levels were 650, which means the HRT regimen I'd been on that semester didn't physically work.

My doc changed it up and it works very well now, but I can attest to the mental calmness that comes with simply knowing you're taking the right steps in your life.
