that movie was awesome, i saw it again like 2 days ago and found it to be just as awesome as it was back when it first came out (i was like 12).
anyway, i think it may be about being alone in general and depressed and the term "cosmic castaway" just emphasizes the feeling of isolation that the subject is feeling (having the cosmos between you and everyone else). as for the chemical references, it could just be talking about medication (like antidepressants)
