I can't find energy to study

[fengc305]

I study online classes and usually I have to watch 3-4 class with each one going from 50m to 1h 15m And each one takes more time to solve questions and summary, and after that I have to study history on my own. I try to take breaks but sometimes I feel more lazy after a break and I recently tried to force myself to studying more but it's really hard . I really need help
