The title seems to mean that the singer wants to encourage someone, maybe a dear person to her or the listener.
The text isn't very long but there are a lot of repeated words as if the singer wanted to make her message clear and understandable.
In the lyrics, the singer suggests that she is afraid of loneliness when she is with the person she is referring to, but remains to support him.

I don't want to be macabre, but it looks like the singer is dying and she's not ready to say goodbye to this loved one, perhaps because she promised to be there at his side all the time.

I think, with the phrase: "Truth left us long ago and I need her tonight because I'm scared of loneliness with you, and I should let it go but all that is left is my perspective, broken and so left behind again." , the singer is accepting the truth, which she has to leave but is not ready and afraid of being alone, but she also knows that this fear must let her go away and focus on the perspective: the only thing left.
