I think this song is about living with bipolar disorder. During his "summer" (manic stage) he's been running so busy from thing to thing that he finally got a minute to sit down. He's been disconnected from everything he loves, been ignoring people who have been close to him, possibly having affairs (other people he never meant).
During his "winter" (depressive stage) he wants to push everyone away from him.
Both manic and depressive stages leave him feeling disconnected like he's been away and out of his head.
