Nostalgic Repetition Disconsolate Disorder

This is a specific definition I have created for something I have been studying for 2 years. I'm 14 years old and tell me what you think about this definition of this "disorder" I have made a name for. Thank you. -Sefinternal

Definition - A repeating factor of thoughts or memories of a specific action, occurrence or a result in a matter at hand that was either bad or good, but the good and bad thoughts result in a manner that feels as a beautiful moment no matter what but also gives the effect of being depressed. Many things can trigger this feeling; such as music or people you know. An odd occurrence of NRDD can also happen when you have the cold because of the last time you've had the cold. The biggest effect I have found is that music that oddly resembles nothing compared to older thoughts or occurrences of you hearing it before can also effect you deeply for reasons that are unknown, which I'm currently still studying upon.

J - I have been feeling a little off lately... Idk what it is, just been thinking of things and getting depressed for no reason that has an odd effect on me.

D - I believe that's called NRDD. or known as Nostalgic Repetition Disconsolate Disorder.
