Sometimes there are moments in my life where sadness just hits me randomly without any reason. My life is going fine. Happy but suddenly I get this burst of depression kind of thing in me. I feel emotionally heavy and I have this. Weird, bad thoughts…

Could the sadness be anything related to absorb energy from environment? And that my aura isn't detoxified yet?
