I suggest you do the things you normally do when it is summer. Unless it includes being outside. You can also learn a new hobby. Like cooking, baking or even knitting. That’s what my sister is doing. She is learning how to bake because when she’s not doing anything, her anxiety is taking it’s toll on her. I am sorry to hear that you are having a hard time this season. I may not know how it feels, but I know what it looks like. There’s always “light” 🙂
