I know this won't help you right now, but for anyone worried about this sort of outcome in the future: there are companies that provide liquidity financing
Basically they send you money while the company is still private, and you pay it back (+ a fee) after the company has exited.
If the financing is 'non-recourse', you won't have to pay it back if there never is an exit, or if there is an exit but one in which you don't make any money (like in this case)
So taking liquidity (if it is non-recourse) de-risks you from these kinds of outcomes.
