Greetings Robert,
Unfortunately, I'm not going to be much help for you seeing that I really need to be able to see this tree in person to offer any constructive advice. Therefore, you need to contact a local certified arborist or your local North Carolina Extension office and have them examine your tree on-site.
Sorry I couldn't be more assistance to you, but it's nearly impossible to diagnose "sick tree" symptoms via the phone or internet - that's why human patients are always required to visit the doctor's office.
Best of luck!
