I was going through a very abusive divorce with a mentally ill woman as well as exploring my own gender issues. Actually I'm still dealing with the abusive woman, and it's 7 years post separation! Anyway, I realized that I was operating on knee-jerk, runaway emotions and felt like I was going to die of stress and pure depression if that didn't stop. So I began to meditate daily, and kept it up solidly for the first year. It completely changed my life.
I recall the first time I noticed really obvious results - my ex had just played yet another abusive hand and I was discussing it with a friend, and I suddenly became aware of how I was feeling deep inside (sick, angry) as well as how I actually wanted to feel. I stopped the conversation and refocused on the beauty in my life, which is the root benefit of meditation - experiencing mindfulness in day to day living. Every moment of awareness reinforces the benefit of meditation.
Taking this to the transitioning experience, I've found that even on days where people very rudely "clocked" me and I felt insecure and uncomfortable, I have been able to realize the deeper, truer blessings in my life that have followed my transition. Regardless of the challenges of being trans, I celebrate the decision to transition and live authentically in my own life as a woman. I don't believe that would have been possible without meditation and deep introspection.
I recommend you try out Insight Meditation app if this is new for you, there are a great many guided meditations within the app to help you get started and stay with your practice.
Good luck!
