Such bad news. I am not in a position to offer a job right now. But I got fired once, I know it can be tough. Try not to follow your emotions too much cause it usually does not help. You are not your emotions. My suggestion would be thinking about people from your close network, engage them on a 1-to-1 talk. Broadcast messages are not much effective, they could also play against you. That said I hope someone is in the position to offer a job or suggest you to their managers.
