This is a plea for a loved one to stay. The speaker is feeling desperate and desperate for their company, and is expressing a desire to remain together no matter what. The speaker is pleading that they should not be left alone in “this abyss”, an emptiness felt by their separation and the lack of companionship they have grown used to. They feel like they cannot live without their life, or their soul, or the person they love. They know separation is unendurable, being without the person they love would be impossible.
