Janina, I was very moved by your writing. As you can see in my writing, I'm on my own journey. One recommendation I would make regarding breathwork is https://breathworkonline.com/ the first session is free and the experience I had was on par with some psychedelic experiences I've had (hopefully that doesn't scare you). I also do Wim Hof's breathing process; as daily maintenance I love it, but not for pushing forward spiritually.
The idea of generational trauma has started pinging on my radar in the last few months and I am preparing to chase that rabbit down its hole in April. We'll see where that goes.
Much love to you, my lady. Keep writing!
