I understand what you are feeling as I felt the same way when my Mom passed. I put her through so much I wasn't the best daughter I feel. But I have to tell myself... Not one of us is born with an instruction book on how to behave, all we can do is be us. Some days I still say I am sorry for something I said or did. We can't be hard on ourselves thou. She loved you very much just as you love your daughter. I also thought how could life go on , then I thought my Mom lost her Mom when she was younger than me and She went on. So we must also! I just hope this makes a bit of sense written to you as I know what I want to say just hard for me to put it in writing. posted with love!
