How did Edgar Casey know the things he knew ?

I am still looking for the anwsers about very wide mood swings but let me start by when and why they started. almost 5 years ago on new years eve I lost my wife while on a mini vacation. it was very sudden and unexpected (health matters) and within the next 5 1/5 months I lost my mother, 2 grandmothers also my aunt and uncle. and now even after all this time has passed I still have uncontrolable mood swings. elated one moment depressed the next. I am still searching for a cure! (without the use of any drugs)

Dear Diary, Was it wrong to do those things to my sister-in-laws shampoo and toothbrush. . . . . ?
