I to have lost my grandmother in May. She passed away from cancer. I miss her alot as well.
Expressing these emotions of greiving are a very healthy process to acceptance. It sounds like your already there. I value your strength. It is okay to miss the one's so dear to you. That's how they carry on in this world after death, through memories.
Thank you for posting your greiving, it inspires me to open and and begin the acceptance process myself. Just where to begin is the hard part.
