When it hit me, it hit me like a truck. I was diagnosed around 35, and after bouncing through the relief, euphoria, and anger (pretty much as OP described them) I was hit with a crushing sense of loss - I literally felt as though someone close to me had died - but who? I was fortunately in therapy as part of my diagnosis, and it took the doctor to say “Who died? You did.” for me to understand. The person I lived my entire life as had ceased to exist - that was a very unhappy person, constantly struggling, constantly suffering for reasons they couldn’t see. But it was me, and now they were gone. It was a brutal experience, but it gave me the freedom to start redefining my life.

You got this. Adrenaline is fuel for the fire.
