[AMAB 25] I've worked out I'm probably a cis male and now I'm depressed. Has anyone had this experience?

Hi,

The last couple of months, I've been struggling with my gender/sexuality. A few weeks ago, I went to an MTF event that made me feel so out of place (no fault of their own) that I decided I was definitely cis. However, ever since then, I've been feeling sick and am a lot more depressed than usual.

Is this normal? Does anyone have any advice.
