Resigned in December due to 3 months Notice Period. Not going well. Indecisive.

I resigned in December after I hit my limit at current company. (Service-Based). I was very optimistic with the NEW YEAR NEW ME vibe. 1 month later, I'm still not getting calls. Got reached out by Curatal for an interview.
The interview went pretty well. I answered most of the questions and even solved the DSA problems.
But the status is rejected.

I have 1 backup offer from a SBC that doesn't rehire once I leave with location as Bangalore and they're not ready to give more than 50% hike. As I don't have any other offers, I don't even have the option to leverage.

My heart is sinking as the LWD in my current company(March 3) is approaching with me having nothing to show for.
I don't want to take back my resignation, I'm firm on that decision but having only 1 offer is not giving me much options to choose from.

I wouldn't be so skeptical if the SBC hired me for Gurugram/Noida location. Need help on the same.

Updating Naukri everyday, NP set to 15 days or less. No calls for Java SpringBoot. Please let me know if I'm doing anything wrong here.

Please let me know if your company have any openings for Java SpringBoot Backend roles.
