According to some earlier studies, persons with lower self-esteem are more prone to mistrust their partner's sentiments when they are experiencing self-doubt. This can occur as a result of projection. Projection is the unconscious process by which we assume that others are thinking or feeling what we are thinking or feeling. For example, if I feel insecure about myself, then I may believe that you don't love me anymore even though this is not something that you have told me. My belief comes from my own feelings of insecurity. If I felt confident about myself, then I wouldn't need to project my fears onto you. Also, certain types of personality disorders involve a preoccupation with one's own feelings and an inability to trust others. These include obsessive-compulsive disorder (OCD) and paranoid personality disorder (PD). Persons with these disorders may experience anxiety when their partners show signs of rejection or indifference. Such symptoms could cause them to misinterpret their partners' actions as intentional acts of abandonment. Finally, depression can make us distrustful of other people's intentions. This is because depressed people often feel empty inside; therefore, any action on the part of someone else might be seen as a rejection proofing their own desire to be alone.
