Just because your agent couldn't sell your book, that doesn't necessarily mean your book is completely dead. You can try querying other agents if there are still publishers they can shop to. You can sub to the smaller presses agents don't typically deal with. You can also self publish your book.
But I do agree with everyone who has suggested you maintain a distance from writing if it really messes up your life to the extent you described. Wait until you can live off your investments, and then retire and write. At least that way, you won't get evicted.
