I’m sorry, but you have NO options for insurance on your husband’s life. He is already ill with a life-threatening illness. That would be like asking about homeowner’s insurance while your house is on fire!
As for your own life, the question is: What would be the purpose of life insurance? Do you have children depending on your income, or an inheritance? If not, don’t pay premiums for life insurance to leave money for a beneficiary. Keep that money to live on.
