Time Managment is an illusion (advice pls)

sooo this is sort of a rant, but im in college studying and working at the same time, like i wake up at 4 am and finish waay too late every day, i love to write fanfiction honestly, but i haven´t written anything i genuinely enjoy for a while other than work docs or school projects. Ive been trying to learn boxing for a while but the schedules always collide and i feel like i have no life or interests anymore. Any tips for this? Or maybe some hobbies i don´t know about i can try?
