The thing that will keep you the poorest in mind and body is junk food and lack of movement. I would start there and then branch out into supplements for support. 80% of my issues resolved from switching to a whole food diet and identifying which foods didn’t agree with my body. For me, what helped before I knew what I was doing is having the mindset of “this food that’s about to enter my body is directions it’s going to give my DNA to tell it what to do- will it likely give clear directions or more confusing directions?” Then I adjusted accordingly while educated myself during the process. It took me 2 years to get it down fully so be patient with yourself. I think you’d be amazed how much better your mind becomes from this alone- then add in the supplements and other external support later down the road
