can't study anymore

Feeling kind of shitty 'cause I can't even study anymore (and that is kind of all that I do trough the week). Idk why I'm like that since I was studying normally some weeks ago, maybe it has something to do with the fact that I am going to the gym less than usual.

I'm kind of f**ked 'cause I have a really difficult test this week, tips for studying more eficiently are accepted
