You may want to contact a licensed life insurance agent in your area that specializes in placing life insurance for people with impaired risk, or high-risk applicants.
A declination from one life insurance carrier may not be a declination for all insurers.
After being declined, keep shopping for life insurance companies that are known to insure impaired risk applicants.
Also, you can try simplified issue life insurance plans or guaranteed issue life insurance, which usually takes most applicants subject to age requirements.
