There’s another issue being discussed about hiding mental illness before marriage which is a terrible thing to do. However, no one is sating that people must get married to people with mental illness.
Of course, no one should hide anything. If people believe they have a mental illness they must discuss it beforehand. However, I must insert here that many people are being misdiagnosed with mental illnesses when most of the time it’s about middos and has nothing to do with mental illness. Technically all human beings can be diagnosed with mental illnesses in one way or another, none of us are perfect.
