献身的 implies devoted, wholehearted service, often with emotional commitment, whereas 没我的 is more about self-negation.
Compound of 没 (ぼつ, 'to sink, to lose oneself') + 我 (が, 'self, ego') + 的 (てき, adjectival suffix). The exact historical derivation is uncertain, but the word follows a common pattern for forming adjectival nouns from Sino-Japanese roots.
