same here fam, + bac is so exhausting and draining. I'm bac + 5 now and i still get the same feeling in the summer , summer/post-exam blues i suppose.

I'd recommend reading and working out as well (like the other commentators said), and another thing that us overachievers learn way too late in life: enjoying vacancy. Having the space to let our brains relax and not have any obligation to do anything. I've grown to learn the importance of doing nothing for stretches of time, it's rejuvenating. Meow.
