Dear Teddy,
I know that past, even if you've already lived it, seems very scary as to what it may unlock.
It's never easy to talk, but you'd never get ready to talk unless you start talking. Start slow. If you get uncomfortable, you can always try next time. But there will be no signal from your body (like a traffic signal) to indicate that you're ready.
Making peace with your past is a slow process. Take baby steps. Test the waters by dipping your fingers in the pool you don't wanna swim in. If you get comfortable over time, you can take a plunge.
Good luck!!
