Exams and severe D3 and b12 defieciency. Any way to lock in and be productive?
So I'm 18f and have been a student studying for competitive exams since a couple of years. Since more than a few months I've been experiencing things like loss of cognitive abilities, feeling very slow in thinking, general fatigue all throughout the day, and as the time went by I started sleeping like 11-12 hrs every single day. Now as there's this grind culture thats very popular in these exam communities as they say "if u wanted to, you would", i ended up in endless cycles of brute forcing myself to study, trying to push myself every single day while blaming everything on me because I was lazy and i didnt work hard enough to blame anyone else. Now I feel helpless. Months have passed and I've lost almost all my exams, even in my drop year where i was supposed to work my ass off. I have nowhere to go and my near future which depended on which uni i get, its all blurred now. I dont know i cant even cry.
In between all of this I finally managed to get my bloodwork done and found my b12 to be 170pg/mL and D3 less than 7ng/mL. My doctor prescribed melcobalmin sublinguals (1500mcg) along with folic acid everyday and 60k d3 talbets once a week.
Its been 3 weeks since then, now I know I need to be patient with the healing but I still have some exams left and those are my last hope. The people around me do not take these deficiencies as seriously, every time I say my head is spinning, i have brainfog or smthg like that, almost all of it gets a "even I feel the same" even if they care, they're like "try to sleep more today" and I just can't, right? its making me feel hopeless and helpless with my body. I'm still sleeping 11-12hrs everyday and I am not able to study. If I don't manage to do something, I fear I might be in a very bad place with my and my family's dreams, and this is breaking me apart. Is there any way I can push myself? I've tried everything but I cant focus for more than a few minutes and the only way I keep myself up is by distracting myself and that is neither helping me, nor the exams.
Thank you so much to this subreddit btw, reading y'alls stories make me feel seen.
