I have difficulties noticing some patterns that affect daily life, like what makes me sad, happy, excited...etc. Until now, for the life of me, I cannot tell whether caffeine affects me or not. I cannot tell whether sugary snacks affect my energy like it does other people. I cannot tell whether exercising actually makes my mood better or not. If I didn't know any better, I might have said it's all placebo.
What I do know is that some days I feel good, some days not so much. Some days I sleep very well, some days I only sleep 3-4 hours. Some days I feel energetic, and some days I don't. But for the life of me, I cannot make sense of it; it all just seems so random, but at the same time, I don't believe in randomness. It must have something to do with what I do every day.
What gives?
