How Do You Deal With Sadness?

I'm dealing with sadness right now. My husband is terminal & I'm waiting on a hospice visit . We are fortunate to have many supportive friends that visit & help with tasks I can't do.... although I was just on a ladder trimming a tree. What helps me is gardening , anything from pulling weeds , planting seeds & flowers. to pruning the climbing roses. Reading is also a nice distraction .So is exercise. Yet, I can't avoid the waves of sadness that grip me. I accept them .
