I know you're only asking for suggestions, but as a disclaimer I'll just say that I understand what works for a person might not work for the next.
I know you told me in your last post you like to take baths. Sometimes, it's really difficult to actually get yourself up and do it, but bubble baths help me SO much. Dimming the lights, lighting a candle you really love the smell of, music/no music (I like no music), as many bubbles as you can handle... When I'm having a panic attack and need some self-care to make it stop, making the water as hot as I can stand helps.
I have asthma, so going for runs isn't an option. I wish it was - it's a great stress relief. I also ######6 hate working out - my mother used to be a bodybuilder (you can imagine the invalidation that came with that) so working out is more of an enemy for me. Lately, I started using my yoga mat and just doing stretches at night. Sometimes I'll use weights, do some sit-ups. Most nights, it just helps to move my body.
Every payday, I like to spend at least $10 on something for myself that will improve my happiness. Sometimes it's a new bath bomb, sometimes it's a cat toy, sometimes it's food. This gives me at least one thing a week that I can do solely for myself. If you don't have a lot of money (I get this - was unemployed for two months recently), even just having a night where you only focus on you helps. I like to make myself a really nice, healthy meal, take a bubble bath, put a ton of lotion on, get in the comfiest pajamas, watch one of my favorite movies (non-triggering!), and maybe even have a beer or two. If you don't like beer, weed. If you don't like weed, a really unhealthy dessert.

For daily activities, though, I tend to gravitate toward easier self-care. I make sure I floss, brush, and use mouthwash every morning. I try to leave enough time in the morning so that I can make myself look how I feel comfortable - not the way I had to look because I didn't have enough time to change it. I'll either make myself a nice breakfast, or grab something quick on the way out. I drink a lot of water everyday (this helps like crazy!), and keep a tally of every bottle I drink. At the end of a long day it's so nice to know that even if you only had three, those three tallies are three things you did to better yourself and your body that day.
It was a long time before I ever gained the energy or love for myself to do any of these things. Different for everybody.
