need advice urgently

so im an M23, and ive been having a really rough time lately. my mom just got hospitalized, cuz she may be suffering from depression (relapse) or some other mental health issues. and she is really the person whom centers my life, and now that she is not well, its really hit me hard. and on the other hand, i have the m23 exams coming, and i cant gather any motivation to study, its like im so distracted, and have such low concentration. and the worst part is i have a uni conditional offer of 44 or im ending up no where, if u ask why so high, its probs cuz i am pursuing medicine. and there is no legit back up. my mom has worked really hard for me to get to this place, and meeting my offer means a lot to her, and to me also, afterall it is the product of 2 exhaustive years of ib which u all are well familiar with. pls help me out here. i have always been an optimistic person, a person who always got their shit together even in the worst times, but with my mom situation, i feel so broken, everything is feeling meaningless.

thank you for reading this msg out. and i'd really appreciate if you coulve give me some advice to get myself back together. and good luck to all the other m23s for this session, no matter waht you're going through, i really hope and pray u make it to the end with the result u desire.
