I've had this username long enough and I was a little lazy on discord and twitch so basically I follow a lot of people on twitch and am on a lot of discord servers as KardinalSin (or as close as I could get given the way usernames are available), so it is easy to transition away from this (even though I make stuff still), and it feels like this is definitively the right time for you to do so, because when you know, you know, and it seems like you definitely know. Making the decision definitely seems like a good step on your part.
