There's something deeply wrong with me and I cant figure out how to fix it

Male here. In second year of college. I feel incredibly stuck in my life right now. Sara masla parhai ka hai. I can't study for the life of me. Pehle ho jati thi parhai in school, but ab i just cant for some reason. College has been so devastating for me, my confidence and my overall personality. Roz jata tha udhr, baith kar socialize karta tha and wapis aa jata tha. Yehi sochta tha ke end per karlunga. This thing has ruined my social life. New friends banane se pehle darr lagta ke what if they ask me my marks or future plans.

I got all this confidence in myself that "im intelligent and parhaku" and this and that from school. I dont even remember ke school mein meri motivation kya hoti thi parhne ki, lekin i did study till 9th at least. 10th mein i started procrastinating. Exams mein kafi cheating hui and i managed to score 400 something marks.

Btw my father doesnt have any established business jiski waja se mein itna chill hoon. We're middle class. My father earns well. He gave me an easy life but i just cant fix myself no matter how much i try.

Even when i have nothing to do, no mobile or pc around, instead of studying, i just start walking, creating imaginary scenarios to entertain myself, Its like i just can't ever allow myself to be bored. And even in extreme boredom, i never resort to parhai.

No one in my family pressures me to study. Because they think since im in college, im mature and i know when to study and when to enjoy which is a reasonable expectation. But even after failing in my college, nobody in my house got strict with me. They see me using my laptop all day and dont say a word.

I dont have any interest in any major fields. All of it is just bland to me. The only thing i was passionate about was army but i have knocking knees and terrible eyesight so there goes that dream.

I have set various motivations for myself to get myself to study yet never have they ever worked. Motivations like

1. Making my father proud
2. Being able to travel the world and financial independence
3. Being able to marry without a significant fear of rejection
4. Having a better social life that what i have now

But my brain, just looks at all of these motivations and says "hmm......🤔🤔" and goes back to procrastinating. I dont understand how can someone be this dheet in something that is going to shape his life.

Im quite certain i have ADHD. Or atleast developed it somewhere during college. Because along with my academic failures, my general IQ and intelligence have dropped drastically. I have to think about basic things for so long to come to conclusions. Even in movies or books, i constantly have to make myself alert of whats going on because my mind never really cares about half the shit i do or watch or read. I find myself looking for things like "*insert movie name* ending explained" which i never had to do for in my entire life. I dont even consume alot of short form content on which i could blame my bad attention span on. It just happened all of a sudden.

What advice would you give me here?
