I also get benefit from natural plant sources and supplements. I'm not saying try any of this, and some of it isn't legal some places. Some places require prescriptions for some things.
Kratom. I use it for chronic pain and depression. The red vein can help when I can't sleep, sometimes. Green and white help with my depression and low energy days.
Kava. This has been an absolute miracle for when I'm having huge anxiety levels. The docs will not give me anti-anxiety meds, benzos specifically, ever since I tried to OD ages ago. I use it maybe once a week and it does help me tremendously. Chronic, heavy use can cause health problems. I'm actually grateful they won't give me benzos, because I get stuck in that trap where my body wants them the next day.
Yerba mate. Natural anti-depressant tea. Mild effects, but also very energising. I have to use with caution because large amounts do tend to push me manic.
5-htp. I use it for depression and anxiety. I get a good mood lift and it helps when I'm having trouble pushing through my day. Some people claim it makes them sleepy. I'm quite the opposite.
Switching gears...
Meditation is so helpful, and writing is good too, even if the only thing I put down is "I don't know what to say" a hundred times. Building electronic circuits is fun and fixing old ones is, too.
In morning yoga today, I completely let go during savasana and have felt VERY good since.
Experiencing the arts helps too.
