SD/NA stands for “self-destructive/negative attitude” and refers to a mindset or behavior that is harmful to oneself and others. It is characterized by a constant focus on the negative aspects of life, a lack of self-care, and a tendency to engage in destructive behaviors. This can include self-sabotage, self-harm, and a pessimistic outlook on life. SD/NA can be a result of past traumas, low self-esteem, or mental health issues. It is important to address and overcome SD/NA in order to lead a healthy and fulfilling life.
