Heavy .... yup ... that alone feelings was really similar to "So quiet its deafening" for me. No matter how much I GAL'd it would only be a band aide for the cancer as far as I was concerned.
If you did not feel this way I would be worried, you just can not stop a long term relationship ... strike that .. have one stopped for you ... and not feel some sort of withdrawls. Its a deep pain, one that new friends and activities will not fill, not at first anyways. Thats where honestly for me the anger fueled me bast those gaps .... I often got to the point of F her this is not going to ruin me nor my life ... she did not define me ... not after she left.
