Is there a project you can try to take on? Like writing for instance, or graphics, or drawing, or baking, or reading, or visiting old / hospitals / babysitting. Kudos for listening to shiurim when you do and it’s perfectly normal that you’ll watch movies some of the time too 😉
Remember also you’re too young to say “you’re wasting your life” – you may be wasting time but you’re life??? Not yet!
Would you want to share where you live? Maybe there’s some other people on here who do to and you can spend time then together ;))))
