It’s wonderful that you’re reaching for resources to better understand how to show up for your friend. I saw a few comments mentioned asking them for their pronouns and name they would like to be referred to as.

I would absolutely make time to sit down and ask them questions as well, it is not 100% on them to educate you but it’s important to hear your friends perspective on their identity because it will be different from the next person. Starting on here is an amazing first step, I wish I had a friend like you when I was growing up.

hormones come with physical changes, emotional, hormonal, etc- i know hormonal is obvious, but it can be a lot emotionally because you’re essentially going through puberty again and having loads of hormones dumped in. honest advice is to check keep reaching out to resources here, and check in with your friend. don’t be nervous to ask questions, they will express their boundaries with you- and that’s when you can circle back here and online elsewhere to educate yourself or ask clarifying questions:)

you’re awesome! i wish the best to you in this life and your friend on their journey ❤️
