Tipp for entering your gender's bathroom as a trans person: either go with a person you trust or leave a person you trust standing before the bathroom so you have someone to help you if there are any problems. There were no problems, but I had my dad wait in front of the bathroom because I was nervous and wanted some security.
Fun fact, Linkin Park was my gateway to harder as well as to softer music:
"One More Light" opened me for softer music.
"Given Up" opened me for harder music. I started listening to Slipknot, and now I listen to Extreme Metal a lot.
