I'll preface this by saying I understand it might be hard to get into this mindset, I'm not trying to be patronizing or reductive of your feelings.
I try to appreciate tiny little things in my day. Pleasant smells, seeing the beauty of everyday items, the warmth of tea, how pretty the sky looks when I happen to notice it.
Along the years I've collected little things that bring me joy to use, like nice dishes and mugs, a pretty pen with a color I love to write my notes in, clothes I feel cozy in. I don't acknowledge them every time I use them, but they bring me little moments of appreciating what I have and the beauty of everyday items.
This is one of those chicken and egg things, I don't know which causes which, I can tell you I consider myself quite happy with my life, I'm very grateful for where I am in life, even though my family and I have been heavy a rough year in terms of circumstances.
As for passions, I love learning and crafting, lately I've been focusing more on sewing, but I haven't had much time to dedicate to it. I like spending time with my husband, just doing boring grown up stuff like buying groceries is better with company :)
I hope you get better soon!
