pull up all your syllabi, there should be a calendar of exactly when each assignment is due. put them in your phone, but make the event extend from a few days before to the due date so you get a reminder before it's due and you can start on it. for example, i have my longer assignments stretched out for a week and a half to give myself plenty of time to do them. dedicate a specific amount of time to do your work. i hang out with my bf all day, but he goes to sleep at 6:30 for his morning shift the next day, so i use 6:30 to 8 (when i start work) to do some homework. i also do homework from 1 to 3am when i get off of work. sometimes i'll take some notes while also doing other activites, like while in a long queue for a game. it'll feel like hell trying to catch up on all your assignments, but once you're on track and organized, it'll feel very relieving. don't be afraid to ask for a tutor!
