On my part, I'd like to bring up something that has caused me some trouble and may or may not be affecting you.
Over the past two years or so, I had been extremely negligent with my academic life. Not as in "I'm going to parties and playing vidya and ignoring uni", but rather as in "I didn't deliver any of the things I said I would this month". Why was that?
That was because I had entered this weird state where instead of consciously putting effort into my work, I was just passively going with the flow. I would read a bit, write a few stuff down, get distracted, reread something, and keep going like this for days and weeks as if I didn't have any control of my own actions. Not only this got me into trouble, but the outcomes of this attitude were making me miserably. I would fail at literally everything I would try, and I couldn't understand why. The worst part? Other people could do it. Normal people, that weren't particularly brilliant or anything, could be successful at the same things I would fail at. It was extremely painful to see myself in such a position and all I could think about throughout all these two years was "what the fuck is wrong with me?"
I've recently snapped out state by growing a stronger awareness of what the real problem was, and since then I've been able to do everything. Just like I always was. I had to re-learn how to stay calm, be confident in my abilities and just take action and do the things I was meant to do.
I don't know what exactly is your issue (feel free to try to explain to us what's going on in detail), but that scenario that you described, of watching everything fall apart in front of your eyes while you feel powerless about it all, really felt just like what I experienced.
