I suggest you regularly going for a walk (at least 30 minutes), in an area with plenty of greenery. Perhaps a park. The change of scene (from being inside) plus the exercise, sunshine and face to face contact with others should help.
I would love to go for a long walk or better run. I have a disability, one of the things that led to this act, that makes walking very painful so I shuffle around short distances often outside to try and get sunshine. It really does help. But I live rural so no other people. Listening to Satie now and just ate an Andes Mint...no dark around. I am trying. Fighting. I am just losing again after already losing one and botching that. At the time I need the most support and love, I have the least. The ironies of my life keep hitting.
