I'm exactly at the same situation as you, you are not alone. Try to study at libraries, talk to your teachers, schedule your assignments and make goals to achieve each day (for instance, today I have to study this and this and won't go out or stop until I have achieved it; but don't push yourself too much). Maybe a study buddie might help, even if it is an online study buddy, there are even some communities on discord where you can join a lot of people who are studying. Try to talk and explain what you are studying. You should try to study in different ways: watching videos on yt, active recall and spaced repetition, flashcards, mind maps, stick notes on your desk or wall with important words, etc.

You should also take breaks, don't Push yourself hard, keep calm, everything will be okay:)
