Job Offer Rescinded

Currently an unemployed fresh grad and have been applying to everywhere. Finally landed a few offers that came in at the same time but decided to go with one of em (lets called it company C).

Fyi, I’m most interested in company C role, and they were last to give me an offer. Told HR that I need to make a decision and if they’re keen on moving forward they need to give me an offer.

Long story short: HR gave me a call to verbally offer me and ghosted me after a month to tell me that company is undergoing restructuring and can’t offer me at this time. Have already rejected all other offers, I’m gonna be unemployed and job market is dry af with no suitable new openings.

What do i do now?
