How do you people manage time?

I have had one successful weight loss episode where I lost around 5 kg (11 lbs) in the lockdown around 2020.
But after that I had to go back to school, do the daily stuff and now I feel I have gained a bit back (around ~ 2kg-3kg) but I just can't manage the time to jog in the morning since I have to get up early, run then go to school and comeback to studying.
This fucks up my sleep schedule pretty bad. What do you think I should do to manage this? I Sleep at around 11 pm, could make it to 10 if I stopped fucking around on the internnet that late.
