Some of the categories of things about which people feel shame:
A) Divorce: When I was a child divorce was rare compared with today. For most people it was embarrassing to admit to divorce. It was not unusual to attempt to hide a divorce from the community. My parents were divorced when I was 3 years old. When I became school age, I was instructed by my family to say that my father had died if asked by the teacher.
B) Mental Illness: Even today, when the public knows more than ever about mental illness, many families continue to maintain a shroud of secrecy around a relative who suffers from one of the psychoses, such as schizophrenia. Years ago these feelings of shame were so powerful that schizophrenic family members were permanently locked away in mental institutions where they were never seen or heard from. Other families locked their mentally ill relative in a room and maintained isolation and secrecy about this person.
C) Rape: I have a number of female patients who were raped either during their early adolescence, late adolescence or adulthood, and who kept the crime a complete secret. These survivors of violent rape attacks blamed themselves for the rape and continued to feel guilty well into late adulthood.
D) Women: Sexual issues and various types of sexually transmitted diseases are sources of extreme shame and embarrassment for women because they fear that they will be judged as promiscuous if they admit to a boyfriend that they have an STD. In this case, I am referring to the less deadly types of STD's such as Chlamydia and herpes, rather than the more serious diseases such as HIV, which has this as well as other issues surrounding it. I have seen many cases in which a woman is reluctant to begin a relationship because she fears rejection if she admits to having an STD.
E) Adoption: Even today, some families treat adoption as something to be ashamed of. Perhaps this has to do with the fear that they will be judged by others for not being able to have their own children. In addition, there are those parents who fear that if their children learn that they are adopted, they will want to find their biological parents and turn away from their adopted ones. As a result, there are those unfortunate families who keep the adoption a secret from their children.
F) Alcoholism or Drug Addiction: Some attempt to hide their drug addiction for fear of losing their jobs and others fear the loss of their loved ones if they admit to their addiction. The fear of judgment is a powerful motivator for secrecy because people find it difficult to admit, even to themselves, that they have an addiction. Yet, the possibility of recovery dictates that the addict recognize the addiction and find help.
G) Job Loss: In our highly competitive society in which success is measured by the amount of money that you make, being laid off, downsized or fired from a job is experienced as extremely painful and leads to feelings of depression for many people. Men feel most stigmatized by losing their jobs because so much of their self worth is measured by their ability to earn a living for their families. There are actually cases in which a father has lied to his children about his work status, pretending to the child that he still has his old job. In one case, the particular father went to work driving a taxi cab, changed his clothes at the garage to fit that of a driver and tried to make a living in this way so that his children and neighbors would not know the truth.
H) Extramarital Affairs: In example number 6 above, the woman lived a double life. The lover knew of the husband and wanted her to leave the marriage and be with him. She didn't want to leave her husband because she did not believe the lover could maintain a serious relationship leading to marriage. In addition, she feared condemnation from everyone and maintained strict secrecy around everything she was doing. She admitted that the entire secret could be discovered by her husband one day but, in fact, she was in denial about this possibility. She was constantly plagued by feelings of guilt, yet, could not stop the affair or leave the marriage.
I) Homosexuality: When I was a young man, studying for my PhD, the head of my dissertation committee admitted to all of us, students and faculty alike, that he had left his marriage of 25 years and his adult daughters, in order to live in a homosexual relationship with his lover. He had kept his real sexual identity hidden from his wife, children, colleagues, and friends, out of feelings of shame and the fear of rejection. It was the era of increased sexual tolerance and greater public awareness that allowed him to "come out of the closet." At first shocked, his daughters later came to accept him and his wife had always suspected something was not quite right.
J) Gambling: Tragically, in case number 7 above, the wife did not learn the full extent of the dire financial situation for herself and the children until after her husband suddenly died of a heart attack. Learning the reality of the situation was disastrous for her and led to a complete life style change due to the seriousness of the debt.
This is not a complete list of all the reasons why families keep secrets. Criminal behavior, violations of the incest taboo, and suicide are additional examples of the many other factors leading to lies and secrets.
