I cant really say i have experienced real depression except for some gloomy days probably because i just spend my whole day doing hobbies... Also, it is very hard to advice you on how to get rid of it, but one thing i'd recommend is having a purpose in your life, connecting with God (if you are religious) and having some hobbies defo help. But if it is some kind of medical depression, it is good to get a treatment (for your own sake, cuz it will get better yk).

Keep your head up lad, better days are coming, you got this❤️
