Antonia, you are so in touch with your feelings, which is a wonderful thing.
I think the bomb and the letting go are both huge. Although I felt a lack of control on the first and a feeling of control on the second. Either way, it is life changing as you are experiencing now.
I always say that we all walk this journey in our own way. My rule of thumb was always to act with dignity, to adhere to my moral compass and to do what was best for me at the time.
I knew if I followed those, I was making the right decision at the time.
I, too, made a conscience decision to let my xh go. It took a long time and great heartache, but, I knew that I loved him enough to let him go and I loved me enough to accept it.
I know you know that you will be ok. This is all part of the process. There will be days of sadness, but, you will begin to feel strong again.
Be kind to yourself, sweetie. You're an amazing person with such wonderful insight and heart.
