Dear Sir,
Welcome, and thank you for trusting us
Sir, what you are going through is a case of obsession. It is an idea takes over your mind and you are certain that it is illogical. This kind of ideas force the person to think of it, however of him realizing that it is nonsense, but he cannot resist it.
For example, there are many kinds of obsession, like the obsession of abilities, obsession of organizing things, obsession of imagination.
Exactly as I said, it is kind of illusions and ideas that the person thinks of it regularly.
Moreover, there are several reasons help with emerging a situation of nervousness, which cause a serotonin deficiency. There are some medicines that help to increase this hormone.
The treatment can be conducted through two ways, the first is psychologically like practicing activities you like, and practice your mind on things you like to do. Knowing that, this situation is a kind of depression. You can also do that by observing your ideas and yourself when doing something rare.
The second is a medicine that a psychiatrist can prescribe it to you after a couple of visits
