My strategies have been honed over 15+ years of depression and anxiety, and most times, keep me going (there are always those unavoidable times where you crash, but using my tools keeps me mostly on track...when I DON'T use my tools, that's another story).
1. Gratitude EVERY DAY. For me that means putting something down, in writing, that I am grateful for, every single day. Even when I'm really reaching for it and I have to write something like, "I'm grateful my pen isn't dead so I can get this gratitude crap over with", lol.
2. Exercise most days. For me, depression leads to insomnia, which makes depression worse, so exercise helps a lot with that. It also helps me feel better in general. I adjust the intensity and time I aim for depending on where I am. On a bad day, it might be "I will walk for 10 minutes, and if I want to stop, I can". I rarely want to, but giving myself permission gets me off the couch. One thing I do when I'm really anxious is picture the exercise actually burning off the anxious energy. It's less about "I have to do this for my weight/health/etc" and more "I have all this uncomfortable anxious energy. Exercising will burn some of it off and make me feel better".
3. Do something just for me, most days. I have a kind of busy life (work, a 2.5 year old, etc) and taking care of me gets pushed by the wayside, plus when I'm depressed the mindset is like, why would I take care of me when I don't really give a crap about me? So sometimes I force it, but I try to do small things. Take a bath. Put a mask on my face. Paint my toenails.
I track all of these things on a Habits app, because doing them regularly helps keep the depression in check, and then it's easier to manage. So every day I check off if I wrote my gratitude, if I got some exercise, if I did something for me. There's a certain motivating factor in ticking off that checkbox, so that helps me keep it up. And I make sure that app has things that are really easy and attainable on it (mine are "Brush Teeth" and "Clean Anything") so if I have a really bad day and don't get to anything else, I can still have some checkmarks before I go to bed.
