Usually the best thing to do is to look for a job that can provide a good source of income, but in emergency situations, there are other possibilities like selling things you do not need or asking for help from someone you trust.
I agree finding a job is better, but you can also sell all your coins on a emergency situation. You should first find a job to secure your coins, because in the future bitcoins price will go up.
If you can't find a job then there is nothing to do but selling your coins. It is painful but emergency is an emergancy.
