Sarah, I completely understand where you are coming from. Time being divided into “before mom was sick” and “after mom was sick” totally resonates with me. In an instant the life you knew and expected is changed forever. I think you are forced to mourn the loss of your hopes and wishes for the future. After my mom died I was in a friends wedding and while the beautiful ceremony was going on all I could think was, I am never going to have this. And I too often feel that others take their relationships for granted. My hope is that I do not. While my mother was here we made the most of the good days and bad days alike. Hopefully having the support of others in your situation will help you feel less lonely. I wish I had been looped into this resource when I was going through everything with my mom.
