1. Derealization

2. Gamomania
If you have met a person who walked up to you and asked you to marry her/him then surely it sounds like that the stranger have gone crazy or is the person suffering from gamomania. This is one mental disorder because of which people make sudden decision without thinking on it just like outrageous marriage proposals. Hence be careful while saying yes to such person, as the problem is quite severe. In such case, if you make him your fiance then you have to accept the fact that he will get a new wife every day. The patients with such disorder have intense desire for marriage. Such patients have the tendency to bend towards a polygamous lifestyle.

People live with this disorder all their lives and suffer few episodes, but they seem to be brought on by trauma, stress, pain. Anti-convulsants and migraine medication are usually prescribed.
12. Walking Corpse disorder
This is one of the lesser known mental problems which is really strange, to say the least. We can only empathize with people who have this. They feel as if their entire body is rotting, and as if they do not exist anymore. This is one of the rare mental health disorders which starts with feelings of self-hatred, and progresses to people experiencing delusions as well as chronic depression. Jules Cotard, the neurologist discovered it and named it ‘The delirium of negation’. The baffling part of this syndrome is that the sufferers also feel as though they are immortal!
13. Dissociative fugue/dissociative amnesia

Psychologists think that this disorder is a way of coping with horrible memories (like trauma during war), and people unconsciously suppress their memories, so that they can function normally. The treatment focuses on accepting the trauma through a targeted therapy process. This is one of the psychological illnesses you didn\’t know about, but spreading awareness of it will help many people.
14. Erotomania
This has become more of a movie staple than a disorder (especially in Bollywood), as we see heroes and heroes suffering from the delusion that the other person is in love with them (belonging to a higher status than them!). Many stalkers probably have this disorder too. The sufferer has such strong delusions that they cannot accept that the object of their adoration feel nothing for them.
15. Derealization/ depersonalization disorder

Sufferers live in limbo, detached from everything and everyone, and feel cut off from everything. Then strangest thing about this disorder is that it has to appear suddenly to classified as DDD. Others reasons for this disorder is emotional abuse during childhood, or a deficit in brain’s emotional nerve centres. People who suffer from PTSD, clinical depression, substance abuse disorders, and patients of epilepsy also can suffer from this lesser known mental problem. Therapy is the treatment as of now.
16. Borderline Personality Disorder
This is a personality disorder which a lot of people suffer from unknowingly. The name is derived from the belief that the disorder was on the borderline between neurosis and psychosis. This is one of those rare mental health disorderswhich is common but most people do not know that it is a mental disorder they are suffering from. Symptoms are volatile mood swings, impulsive behavior, unstable relationships as well as viewing things in extremes. The patients find it hard to control their behavior, and suffer from terrible bouts of depression, anger and anxiety. People with this disorder also self-harm such as cutting themselves, have a very high suicide risk, especially those who are in their teens or early adulthood.
17. Complex PTSD

18. Dependent Personality Disorder
Personality disorders such as this one can exist in absolutely normal people. If these disorders are not treated, then it has a crippling effect on the sufferer and it’s difficult for people around them too. People who have this disorder want others to take care of them, excessively. They are submissive, needy, clinging and fear being abandoned. They shirk from responsibilities, need constant approval and reassurance. Remind you of someone you know? You definitely know someone who displays these behaviors in your family or friend circle.
