We are all scared, it comes with the territory and is completely understandable. Sure, we LBH got some things wrong but it's not all our problem. I was telling my my therapist yesterday that this was the first week in my sitch where I started feeling like it wasn't all me and that my W might actually have some fault as well. I keep thinking how could I have pushed away the most important person in my life and these thoughts crush me. However, she also could have approached the sitch with solutions that were more positive and she didn't which demonstrates that she is also accountable for the failing M.
You have found strength in the fact that you have not lost yourself. This is good, this is attractive, this is where you need to be. This is where I want to be!
