Ruby, sorry I missed this thread entirely, not sure how.
I really hope you are getting along okay- not sure when the actual anniversary was... I like the idea of doing something special in the day to remember her by, if you did, i hope you found some comfort.
I suppose the idea of "time being a healer" follows in that logically, the 1st anniversary would be the hardest- (feeling it myself at the moment, for different reasons,) so I hope it eases with time for you hun.
As others have said, focus on the lovely memories, and the special times you spent together, you sound as if you had a truly wonderful friendship. Much love, Lorri xx
