hey i feel you! honestly i've started hating the summer for this exact reason. i had planned on doing so many things in this summer before uni starts but it feels like i've done basically nothing, but we do still have time! i remember the summer before my a-levels, i put off my transition work till literally the last week. what i ended up doing was getting noise cancelling headphones and finding one song to put on repeat till i finished it.
other, perhaps less dysfunctional strategies i've found useful are splitting things up and just making a start, even if its something really small. also to use as much scaffolding as you need, because it honestly doesn't matter about "cheating" at this stage - if you heavily reference something, just reference it using harvard referencing or sm and you're golden. my big hurdle is not knowing where or how to start, so overcoming that will probably help you. setting a schedule might also be of use, the way i like to do it is write on a calender what (small) tasks i need to do per day, so that im not facing down a huge list of jobs that all seem unapproachable. good luck and i hope this helped! let me know if you'd like any other advice or tips <3
