Your bash is now stopped (as in process state). To revive it, you need to send SIGCONT. That probably means you will need some other shell to kill -18 (which is SIGCONT) your bash. If there is no way to obtain a shell, you will likely have to power cycle the machine with all the implied consequences (possible data loss).
If you want to shutdown forcefully and are sure there is no other way, hold the power button for ~4 seconds.
