Difference betweeen regret and feeling a feeling all the way through

This month’s topic brings up a lot of feelings about how I have spent my past 47 years. I have spent a lot of time buffering, comparing myself to others, and probably subconsciously trying to get the attention from others I did not receive as a child. I have a lot of strong feelings ofsadness and actually regret about this. I am curious what Brooke would say the difference between feeling that feeling all the way through and living in regret is. Thank you for your answers 🙂
