In the old days I would have a lot of anxiety in the summer because I wasn't doing all the things I could or should have been doing. Mowing the lawn, painting the house, going to the beach, kayaking, hiking, whatever. Now I rejoice in my sloth and just enjoy soaking up the sunshine in my backyard without guilt or fear. I used to suffer from some pretty serious seasonal depression in the spring, but that seems to have evened out, although I don't know why. I am sorry you are suffering and wish you the best.
