Call your Dr's office and tell them you need to speak to a social worker. They should be able to help you with resources to assist both of you.
If you or your husband are a veteran, call the nearest VA hospital and ask for a social worker. The VA offers caregiver help too.
Also, pallative care can be very helpful. You don't need to have a terminal illness to receive their help.
Hoping that you receive the help you need.
