Domestic Subway Lyrics
but still you are lonely and noone listens to the things that you say
depression is a lesson that you really gotta hold on to
or is it fucked up anyway for you
because you're messed up and you're lost in other peoples thoughts
you're looking around for directions and clues
but you should look somewhere else
cause somewhere inside you you can find the strength you are searching for
or is it fucked up anyway for you
The author is addressing someone ("You"), analysing his being lost in his own thoughts. Since the author is known to express his feelings one can assume he is talking to himself. Either that or to a close friend, since he seems to know the person quite well. That person he talks to is feeling bad, which is described using words like "depression", "lonely", "messed up" etc.. Especially the term "depression" leads to the assumption the person is experiencing a phase of disorientation and self-centeredness, that is so typical for teenagers looking for a meaning in their lives. "Depression" or "being depressive" is - in my own experience - often used in an inflationary way by young people, whose thoughts just circle about themselves in self-pity.
In a nutshell - the person addressed is drowning in self-pity trying to figure out the ins and outs of life, but failing, since he's caught in the vicious circle of his own thoughts.
Cheers!
