Thanks DF90 for putting an end to that.
If you're not trans, this thread probably isn't for you since the question is specifically for trans folks.
To answer the question, I'm transmasculine and non-binary (my pronouns are they/them/theirs). Gender identity and expression--and the pressures to conform that stem from the ways in which society pressures binary gender presentation--have certainly played a role in my depression throughout my life, especially as I hit puberty and as a teen and young adult. They still do sometimes, but to a much lesser extent.
At the same time, I am greatly appreciative of the insights into myself that being trans has forced me to unearth, and for helping me to see better how oppressions (and privileges, since I've been read as a man for the past 10 years and I'm white) interact. I couldn't have become comfortable with being trans alone--it took finding and building community, as well as shedding a lot of "friends" and some family.
In all, I've worked out and eliminated most of my own internalized transphobia (e.g., nowadays fear, rather than shame keeps my clothing "gender conforming"), so it's more so a complicating part of my life than a reason to CTB.
