What do I have? depression problems?

Sometimes i get so depressed i feel numb and dizzy . i get depressed for no reason. just for the simple reason im not thinkin positive anymore. most people put on their favv movie or listen to music but i get so depressed my fav movie doesnt make me laugh, being with friends doesnt make me laugh, i dont smile, i jjust pout and have difficuluty sleepin or makin sense. i turn into a hot mess. idk what i have or how to help myself, kickin the walls and releasing anger helps but its like waht am i even angry about? idk how i get in these emotional ruts.
