Tough all around

I am struggling to find joy. It seems like everything is hard now. Teaching is a disaster, and I'm too close to retirement to switch jobs. My marriage is challenging. My Mother is in a nursing home. My daughter struggles with anxiety (although my daughter is the bright light and my reason for everything). My Dad needs us around, and we don't have time or are too tired to socialize. I tried therapy, but I'm just too wrapped up in the bad to want to do anything else. I do feeun things, but continue to be anxious about everything else. I love my husband, and worry about when the shoe will drop again, and have a hard time letting go of what's past because of it or vice versa.
