Can anyone tell me why i cant study why im not motivated ?

Ok, so 2mrr are my midterms in the college. But i dont know why i havent been able to study since i entered college, everytime i come home i say im going to study and do my best and then when i get here i just sit and stare at my work and do nothing at all. this happens all the time on thursdays is is my last day of cl i only go monday through thursday to college and when i get home on thursday i always say im going to do all my HW so i can be done by friday night and instead i slack of again and say im going to do it 2mrr then on friday i say the same thing and then on saturday i say the same n then when its sunday i just sit and wonder and dont feel like doing nothing at all and all i can think is that i hate all this stuff like i dont understand myself why dont i feel motivated to do my work and study is so weird...
