In the song "Drug Abuse" by Brynn Mice, the lyrics seem to convey a feeling of exhaustion and frustration with internal struggles and using substances to cope with them. The singer expresses a sense of keeping their emotions and struggles to themselves, sweeping them under the rug and making excuses to avoid addressing them. There is a sense of feeling overused and worn down by these patterns of behavior. The lyrics also hint at the underlying reasons for these struggles, such as always being on edge and staying up at night, as well as a mention of something under the bed and using drug abuse as an excuse when there's nothing to do. This suggests the theme of using drugs as a means of escaping or coping with internal turmoil and boredom. Overall, the song seems to confront the issue of using drugs as a way to avoid facing and addressing personal struggles and difficult emotions. It paints a picture of someone caught in a cycle of self-destructive behavior, looking for an escape from their inner turmoil.
