Although the phrase “feel oneself” (or “feel like oneself”) exists in English, it means something else. Apart from its possible use as a sexual euphemism (“to feel oneself” could be interpreted as a euphemism for masturbation), it means “to feel normal, to be in one’s usual mood” and is usually used in the negative, as in

I feel well = I feel in good health, as opposed to being ill
