i think i've lost my passion to live (no sh/ no suicidal intent)

i used to be so passionate about education and just life in general when i was around 13-14 and then i got depressed. i feel like because i have spent so many years depressed and living my life on autopilot, i truly don't feel genuine joy anymore in anything i do. it's really bizarre and i just wanna be passionate and excited in life, again. i also don't think i know what i like anymore. anyone else feeling this way? advice on how to stop it bcos i'm only 18
