The lyrics explore the complexities of navigating personal relationships during periods of emotional instability. The artist uses the metaphor of a "sunny day" to represent better times or moods, promising to improve her behavior once this metaphorical sunshine arrives. She acknowledges her tendency to treat her friends unfairly during her low periods and apologizes for it, expressing a desire for physical closeness and comfort from them. She also seems to be battling with feelings of isolation, making it clear that she feels alone even when surrounded by others. Ultimately, the song is a raw and honest portrayal of struggling with emotional health and its impact on interpersonal relationships.
