Agree with Doomed, but I'll get more specific:.
When I first hear the lyrics I thought right away "drug/alcohol addiction". So I also agree with Ghostman66's take as well.
"Watched your fears become your god" - in 12-step programs you learn that a "higher power" (basically a god) is in control of you, and you have no control over the shitty things that happen in your life. Instead, the lyrics say - your fears are controling you, causing you to use drugs/alcohol.
"Overwhelmed, you chose to run
Apathetic to the stunned" - choose to run away from your problems by getting high, not seeming to care what it does to those around you.
"Yes it hurts to know you're bought" - basically a slave to the drug.
