Happy birthday weekend, Julia darling!!! I hope you have so much fun!!!!
I think these thoughts that you are journaling are just part of the process. I definitely realized many mistakes I made in the past that I didn't recognize at the time. I think for me this processing really helped me think through how I contributed to my situation and how I'd like to do things differently in the future when I'm interacting with fellow humans But please remember that what happened is only 50% our responsibility, and no more.
