Your list is a very good list. I'm sorry to read you've had a relapse, but it really looks like you're on a good road now. This Summer I made some changes as well, and have been feeling loads better since. I found acupuncture to be especially helpful, but I had a lot of stagnation in my body. I totally connect with the "stop telling yourself you're depressed". The expectation that oh oh everything is going to turn to shit now oh no can really spiral a tolerably bad day/situation into something much worse.

Also, one thing I've been doing for about a month now, and that I feel has really given me an extra boost of energy, is a morning drink. One third/half teaspoon of cumin, juice of one lime/half lemon, and some slices of ginger. I just add hot water and sip it while getting up and about and making breakfast. The bonus on top of the extra energy is that my period pains have just about nearly disappeared. They have always been very bad, but the last time I didn't even feel the need for pain killers, for the first time in my life. And this is a thing that's made me physically unable to get out of bed before, and very often had me unable to straighten up fully. It took a couple of weeks before I really started to notice the effects, but it's definitely a habit I'm keeping.

I've also found that St John's Wort really dampened my anxiety.
