Termination of parental rights; no irreconcilable conflict between the trial court's finding that respondent willfully failed to make reasonable progress under N.C.G.S. 7B-1111(a)(2) and finding that she was unable to provide proper care and supervision under N.C.G.S. 7B-1111(a)(6); sufficiency of dispositional findings under N.C.G.S. 7B-1110(a); lack of adoptive placement is not a bar to terminating parental rights.
