Please help

I am preparing for a competitive exam and I am not able to study. Somedays I just study for 1 hour hardly and somedays i don't study at all. I don't know what to do at this point. My exams are just 1 month away and now it feels impossible. I have like 300 lectures to watch out of 500. I have wasted 5 months and everytime it's the same. I have tried a lot of things to study but it's like my mind just don't want to study. I have little to no difficulty understanding the concept but the problem is I don't study. Now I feel hopeless. I can still try but I fall back into my old habits and can't even stay consistent. I feel pathetic because no matter how hard I try at the moment, next moment everything is just the same. I don't know how am I going to do anything if I can't even study. I really need help. I am tired of living this way. I don't want to be in this loop anymore.
