I'm average and struggling academically

I won't dive deep into my personal issues. I just need help or motivation as I'm being succumbed to this nasty feeling of being a failure and falling behind not knowing what to do with this life of mine.

I think that I'm too old for not knowing how to frame my answers, I write in short paragraphs as you can see. I'm a 20F pursuing ba prog (pol & eco) ncweb. I feel inferior to my peers, those who are hindi medium and they get above 7 cgpa. I have no reason to judge them they're doing great. Well I'm the one to takes things lightly then complain.

Pol.Sci is my major yet I'm embarrassed that I don't know much about politics. All the things I study are automatically erased from my memory as the semester changes. I'm utterly clueless every sem in econ cls. It's my last semester what I'm gonna do? I can't rote learn stuff. I have low attention span and I give up easily. I want to score better grades. I have the liberty and I'm not utilising my time wisely while I'm aware it's harmful.

Tldr; Op suffers from depression, Inferior complex, and struggling academically need tips on how to frame long answers in pol.sci and eco. Ty for your time 🩷
