I think the song is about not taking ownership of needs and emotions.
About feeling isolated and waiting for other people to make the first move and not taking ownership and reaching out ourselves.
Of the desperate need for other people to make us feel loved, fearing lack of acceptance and withdrawing even more,
The more withdrawn we become the less we feel accepted, and so it spirals down. Eventually even when our friends do reach out we are so withdrawn that we "get my machine to let them in"
