Seriously need help.?

the other day i went to feed my pet oyster franklin. i had often talked to franklin about my life with little to no response. but today when i told him i thought to have sprouted a 4th ball he began to weep. i begged him to tell me what was wrong but he turned the cold shoulder, after hours of prying he finaly went on to tell me that he was diagnosed with cancer and aids and wasnt going to live through the week. i was stunned and he was shell shocked. we both created a bucket list but as we finished the 3rd activity he had a heart attack and as he was dying in my arms he told me to keep my chin up and that God loves me, and to try and forget about him. why cant i let go please help!!!
