2024 graduate, no offer in hand,everything seems fkd up

I graduated in 2024 May and I was selected by capgemini but they revoked my offer without a reason i tried reaching out but nothing worked, during mid June my father got really sick and had to be hospitalized so I was needed at home and those times took a real toll on my mental health and i couldn't jump back to my placement studies. Next day after coming back home from hospital I got a mail from tcs that I have an interview scheduled in pune and I had to to travel overnight but I wasn't prepared at all so interview went horrible. After two weeks we decided to go for training institute and started my training online in August since I had be at home for my dad and completed last month and placement have also started but they're offering way too low packages and when I reached out to the institute they said placement team works from home and you need to mail then about your concerns, so what I think is that they must be sending job openings straight from LinkedIn which even I could've done and now if I do any other course or join any other institute it will be waste of time and money. I try applying through job boards but they just don't work at all. Now I don't know what to do I'm loosing my hopes tbh.
