I am sorry to hear about your circumstances- however - it is important to read the fine print regarding your purchase. On the Jetblue website it says this regarding their fares:

JetBlue offers two types of fares: Nonrefundable and Refundable. For JetBlue Nonrefundable Fares, changes or cancellations can be made prior to scheduled departure for a fee of $100 per person on jetblue.com or by calling 1-800-JETBLUE (538-2583), plus any applicable difference in airfare. Any remaining balance will be placed in a JetBlue air-only credit and may be applied toward future travel for one year from date of issuance. If a nonrefundable reservation is not changed or cancelled prior to scheduled departure, all money associated with the reservation is forfeited. For JetBlue Refundable Fares, changes and cancellations, for a full refund, are permitted prior to scheduled departure. Such changes are subject to availability and any applicable difference in airfare (if there is a change in city pairs). If a refundable reservation is not changed or cancelled prior to scheduled departure, all money associated with the reservation will be placed in a JetBlue air-only credit and may be applied toward future travel for one year from date of issuance. Refundable Fares may not be available on all flights.

Notice that it does state that a fee will be assessed if you cancel.
