What are you definitions of nihilism, annihilationism, eternalism?
I don't use the term nihilism at all - and I don't recall where the Buddha ever used it either.

uccheda-vāda (Skt., the teaching of cutting off). Also known as uccheda-dṛṣṭi, ‘the doctrine of Annihilationism’, one of the ‘two extremes’ condemned by the Buddha. This is the view that there is no rebirth or fruition of karma, and that the individual is utterly annihilated at death. It is considered especially pernicious since it encourages moral irresponsibility and hedonism. The Buddha raised two objections to this notion: that it is disproved by recollection of past lives, and it implies the existence of a self (ātman) that is destroyed at death. The other extreme view is Eternalism (śāśvata-vāda).śāśvata-vāda (Skt.; Pāli, sassatavāda). Eternalism, one of the two ‘extreme views’ condemned by the Buddha, the other being Annihilationism (uccheda-vāda). Eternalism postulates the existence of a self (ātman) that is eternal and unchanging, while the latter postulates the existence of a self that is cut off and utterly destroyed at death. According to the Buddha, both of these two extremes misrepresent the reality of the situation and the truth of the matter is to be found by reference to the principle of the ‘Middle Way’ (madhyamā-pratipad). Thus the self is neither eternal nor is it cut off at death: rather there is a dynamic continuity of the individual from one life to the next."
How does your understanding hold up, if you considered that there never was a self in the first place - either to be annihilated or to continue on unchanging? .... all that exists are latent tendencies and kammic accumulations - no me, no you, no one.
