Meh, it's just that time of year.
You can't see this ending any time soon, so your sick and tired of it, and can't wait for it to be over, the weather is **** and you desperately want summer, and now all the teachers are trying that final push to get you through your June exams.
It's not great admittedly, but it's only going to get better. Doesn't your school have loads of chill time / games / genuinely fun stuff to be doing towards the end of the year?
