Guys... Just a help..

I know this might not be a appropriate place or sub to say like this.. I know I should study now... but.. for couple of days.. I'm just feeling very lost... and lack of any kind of motivation (I know some might say why you need motivation to study) . I don't need motivation to learn stuff, I like to learn things , not random things, mainly Computer related... I am preparing for IAT , but it feels like I know nothing... I love to learn about physics , do experiments , but I can't just solve numericals or problems on a sheet of paper for days and days... It is just not me... Can anyone just tell me how I could restore my motivation...
