Is it grammatically correct to say "I was enthused" rather than "I was enthusiastic"?
If so, what is the difference between the two?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
The answer is one of preference, not grammar.
Enthused is a back-formation. Because it's newer, some people may be more used to hearing enthusiastic. Also, as the quote below indicates, the two words can have different implications.
