Pre-Adult Syndrome

Refers to feeling Depressed, Horny, Anxious, unprepared, and or lonely due to being at an age where you are transitioning between child and adult, usually between 18-26.

I am sorry, but these feelings you are suffering from are often those associated with "Pre-Adult Syndrome" and the uneasiness of not knowing what your future will look like.
