Traumatically is the adverb from traumatic. It says that something happened in a way that caused lasting shock or damage — not just that it was unpleasant, but that it left a mark. You will meet it mostly in two places. In medical and legal writing it means 'by physical injury': 'the tooth was traumatically damaged', 'a traumatically induced fracture' — that is, caused by a blow or a wound rather than by illness or age. In ordinary writing it describes how an event affected someone: 'their childhood ended traumatically', 'she was traumatically separated from her family'. Be honest with yourself about how rare this word is. English speakers reach for 'a traumatic X' far more often than 'traumatically'. Most of the time you would say 'it was traumatic when they left' rather than 'they left traumatically'. So learn to recognise it, and do not force it into your own sentences — the adjective almost always sounds more natural.
