A trial court may consider a parent's mental state as endangering to her children's well-being, and a parent's lack of progress in managing her mental-health conditions is relevant to the best-interest determination. See In re R.M., No. 02-18-00077-CV, 2018 WL 3468464, at *8-9 (Tex. App.—Fort Worth July 19, 2018, no pet.) (mem. op.); In re J.I.T.P., 99 S.W.3d at 845-48; In re C.D., 664 S.W.2d 851, 853 (Tex. App.—Fort Worth 1984, no writ) ("While mental incompetence or mental illness alone are not grounds for termination of the parent-child relationship, when a parent's mental state allows h[er] to engage in conduct which endangers the physical or emotional well-being of the child, that conduct has bearing on the advisability of terminating the parent's rights.").
