When Indy passed, to help with the grief and guilt, UConnGSD recommended the following for me. It really helped then, and if I start getting into a funk, I still use it. I thought I would re-post that, since it might be helpful for others.
She recommended that I use two Bach remedies - Star of Bethlehem for grief, and Pine for guilt.
I got a separate small dropper bottle from the health food store and put some purified water, and put 5 drops of each in it. Throughout the day, take 4 drops.
