invisible struggles

What triggers this feeling of being overwhelmed for no reason? From an outside perspective, there is no objective reason things should feel so heavy. My circumstances have not markedly changed. There are no notable stressors present. Yet, internally, everything seems foggy, fuzzy, and oppressive. On these overwhelming days, I want so badly to grasp why I feel this way or make sense of some cause, yet no cause or reason can be found. The only reasonable response is rebellion through persistent, passionate, and lucid living despite it all.
