Can sue for wongful termination

North Carolina is an employment-at-will state where an employee can be fired at any time for any reason.  You can be fired for a good reason, a bad reason or no reason at all. You can only file a wrongful firing claim when you can show the termination was motivated by an unlawful reason.  There are only two unlawful reasons in this state: unlawful discrimination or unlawful retaliation. Discrimination is unlawful only if it is based on things such as race, sex, disability etc. Retaliation is unlawful only if it is based on the employee engaging a protected activity such as filing for workers comp, using FMLA, complaining about unlawful discrimination etc.  I see neither of these in your post, but if you believe either motivated your termination, you should set a consultation with an experienced employment attorney.
