The song is about getting high off marijuana to forget your troubles and depression. The person just wants out of the problems and ordeals caused by people in their life. They are hiding from their problems from being stoned, 'I want to feel like this for a year'.
The last part is about having a breakdown (either high or not) and gaining a new perspective on life and depression afterwards. The person can move forward fresh 'zero the miles'. The heroes probably stand for the people that help someone out of depression and love them. They help the person start over mentally with a fresh slate even if it starts with a painful mental breakdown.

It's an amazingly beautiful song.
