There's lots of good advice here already - let me add one, for the supplement lovers: Find a good probiotic and run with it for a few months. You might feel some benefits for mood after only a couple days. I've tried a lot of supplements in the last few years (any kind of vitamin, and some broadest-band multivitamins, even methylation stuff like Methyl-B12, Folate, active B6) - but the only ones that really made an impact were probiotics. My favorite probiotics are Mutaflor and Prescript Assist, both costing ~€1 per day - but they are so worth it. Call me a lunatic, but they affect my mood in different ways. Mutaflor makes me grateful for things, and P.A. gives me focus and a sense of purpose in life.
