Hi @utopia, also hearing your current feelings. As @Owlunar said, clothes sound like a first step to me. It was a first step out of my worst years of major depression. Op shops are my clothes indulgence, in bursts. I have a happy wardrobe now compared to the nothing I had to wear outside of the home at the end of that worst time.
I also buy second hand, and cheap new clothes on ebay. There have been some items that haven't worked for me when they arrived, but overall I have been satisfied with online shopping. I only buy things that give measurements, so I can check them on myself for sizing.
Sorry you are going through this. Interesting that the mood stabiliser helped for quite some time. Sounds like the circumstances of your life, with covid and all, have become harder. Hope your psychiatrist appointment goes really well with better medication options that may help you more.
