Healing past trauma: listener question

Hi lovely Clare, your video on generational healing was so timely for me. I recently met a homeopath for my son. She was very intuitive and told me that his 'autism' is not really autism but rather a result of generational trauma! She said in order for him to heal that I need to go into long term therapy to have someone connect me back to my heart space and my feelings. She said I am traumatised and emotionally disconnected and this has been passed down from my parents/grandparents etc due to holocaust stuff which is all over my family from both sides where everyone was completely traumatised and on the run. And that now I am on the run and cant settle anywhere. And this is why my son cant develop because he is too busy coping with such a chaotic environment. Everything she said felt so true. 

Would you agree that I need to feel all the pain (my own and that of past generations) in order to heal?? Must I really go sit in therapy for months and feel the pain ?! It feels like the answer is yes and I do feel like I am in constant fight flight barely keeping things together. And it feels like so much sadness does need to be felt and expressed. But Im so confused and really dont want to get caught up in stories. What is true here? Is it just to feel the emotions from an impersonal perspective? Feel the raw feeling without getting attached to any story? This feels like it would be almost impossible. I would love your view on this!
