I appreciate you reaching out and sharing your concerns about your father's recent behavior. It's evident that you care deeply for your parents and are navigating a challenging situation. In such cases, it's essential to approach the matter with empathy and patience. Consider expressing your feelings calmly in a non-confrontational manner, emphasizing your desire for understanding and connection. If communication remains difficult, seeking the assistance of a professional mediator or family therapist may provide a neutral and supportive space to address underlying issues. Remember, these situations require time and effort, and seeking professional guidance can be a constructive step forward. You can talk to me regarding this as i have experienced with this.
