Losing hope

I recently finished my undergrad med school, and I am in the process of preparing for the upcoming entrance exam for postgraduation , which will be held in March next year. I already took 2 exams for 2 different universities. The first one which I took right after finishing my internship( may 2022) got me 95k rank and in the second one (nov 2022) I got 24k rank . Even though I improved my rank , I lost my confidence after the result. This will be my 3rd exam and the 2nd attempt of my 1st exam. The competition is crazy. I am interested in doing internal medicine for my postgraduate course. For that I need atleast 500 rank to get admission in a pronounced institution . The thing is I finished my ug in the most prestigious college of my state with an excellent entrance marks. This has got many people to expect a lot from me. And I too want to study in the same college. These last 4 months I didn't utilize my time properly for studies because of various personal reasons and after my nov exam results , my faith is gone to say the least . I was crying for 2 whole days. Now my granny fell down from stairs and got ribs fracture . She is admitted in icu . This adds more to my stress . I am currently residing in a city 5 hrs distance from my hometown for preparation. Because of my granny I came to my hometown now. Thankfully she is doing fine now except for the pain. But someone has to be with her all the time . I am giving priority to my family right now but I am scared and stressed about my carrier. Can somebody share your thoughts?
