I'm completely there with LadyOracle for what to try when you find things are hard to control and to comprehend.
When I started my transitioning, I wrote... A lot. I wrote in present moment, how I am feeling right now, and how that makes me feel about myself, whatever is bothering me, etc. I never dismiss the feeling though, whatever heightened mood that I am in, because a long as I am on hormones this will be a normal for me, so I will need to understand if there is something in my life that is causing this.
