Once I was more comfortable with the process, I was more comfortable with T as well. Part of just dropping my guard and "just doing it" for me was absolute desperation. I was at a point where it really seemed like it was inevitable that I was going to kill myself at some point. It was quite literally a do or die situation for me. Any risk seemed worthwhile at that point.
