whats wrong with me

recently ive been feeling really tired and lazy, idk why. (14f)

even though ive slept 10+ hours a day, i still fill tired. no matter how long I sleep during the night or day, ill feel really tired, like im not able to do daily activities and feel too lazy to do simple things around the house. i just use my phone a lot and lie in bed and play games, doing only the basic things such as eat and sleep. (sometimes i get too lazy to even shower) my life has been really mundane lately and idk how to overcome this. i do see people saying to go out more and to exercise but i cant find the motivation to do such things. i used to work out a little at home last year but stopped this year. around last month i wanted to continue working out but i just never found the motivation and energy for it... ive also got quite a few things on my todo list (mostly hobbies and fun activities) but up till now, i havent started on any of those

i really dk whats wrong with me , and maybe its because of this i slacked for my exams and didn't score well, which led to me being kinda sad and thinking im not good enough, which further worsens how i feel. idk tho, im just guessing.

ps i have no suicidal thoughts and i dont sh

and to add on, my mother keeps telling me to have dreams and have a plan for life, and to not sleep/be on my phone so much. but i have no dreams and no hobbies and the only thing i want to do life is to travel the world but idk about that anymore
