Dear Evelyn,
One of the reoccurring themes I notice for those of us who have lit 70 candles is that it becomes more of a challenge to find meaning in our lives. I believe that that meaning comes more and more from what is inside us and less about what we do.
If you have a faith tradition, how can to tap into it? A way to start is with meditation. Sit for 20 minutes, noticing your breath, letting go of thoughts. I am amazed how this brings me to a place of contentment and peace both at the moment of meditation and at other times during the day. New insights and peace flow over me. Then there is prayer. There's no 'right' way to do it, so follow however you feel called to communicate with a higher being (which I call God, although the name doesn't matter).
As a prayer person I pray that you will be lifted from this depression and find purpose. I have faith that things will shift for you. Bobbi
