Unemployed since 3 months

I quit my last company in Dec 2023 due to some reasons. I was not aware the market would be this bad. Basically in a nutshell I have at least given interviews in 10-15 companies till now, cleared most of theirs all rounds, but for some reason or other they didn’t release an offer. some feedback includes, why do you want to join us with such less hike, you would leave us in few months. One said they are not able to get final sign off from their lord in US. And mostly others just stopped responding. ATM I don’t understand anything, emergency funds getting over, and realised all the network I made till now in my career and whom I helped are of no use. I know I wont get any clear advice here also, but just venting out. I am on the brink of just quitting everything of this corporate drama and start prepping for govt exam, or start a small biz in my town
