One of his interviews he kind of explains as his song writing is how he felt at a certain time and if only one person said I understand what you're feeling because that person is in the same place and the song only made sense to that person then Chris felt as if he was not all that crazy to feel that and thousands of people felt the same way hearing the lyrics
And I think what you are describing there is what made grunge in general, and Cornell's music in particular so appealing to many. It was real, relatable expression of what many were going through in their own lives.
That said, feelings for his family should have been a prime consideration. Maybe they were; we will perhaps never know. Whether it was accidental overmedication, or what- one thing is sure- it's remarkably sad for fans- can only imagine what his family is going through.
