Yea, as I have learned so far = just be. Do they need to know what is going on? I say don't say anything until they mention something. Why do they need to know your personal issues? Honestly, I am tired of binaries. This age is about moving beyond the 2 and moving onto the infinite. Basically, don't worry about it until it is time to. You cause yourself unnecessary stress otherwise. Just be. Worrying is common, but honestly, changes by testosterone are varying. You wont know until you are on it yourself how fast it will effect you. None of us can dictate. Similar experiences, to me, are... only let it out unless it needs to be. A few months on T could lower your voice or not, even cis-males take years to drop, lol my fav example is Ralph Macchio. Don't worry til it comes. And when that does come, we can be here to help.
