While writing unsent letters can be therapeutic and provide an outlet for pent-up emotions, there are potential drawbacks associated with this practice. One significant drawback is that it may lead to bottling up emotions rather than addressing them directly with the intended recipient. Constantly expressing oneself through unsent letters without engaging in open communication can create a false sense of resolution while avoiding real-life interactions that may be necessary for personal growth and relationship development. Additionally, relying solely on unsent letters as a form of emotional expression may hinder one's ability to effectively communicate face-to-face or resolve conflicts constructively.
