"So" is fine, it means "very" or, as you say, "really".

The American Heritage Dictionary says:

Critics have sometimes objected to the use of so as an intensive meaning "to a great degree or extent," as in We were so relieved to learn that the deadline had been extended. This usage is most common in informal contexts, perhaps because, unlike the neutral very, it presumes that the listener or reader will be sympathetic to the speaker's evaluation of the situation. Thus one would be more apt to say It was so unfair of them not to invite you than to say It was so fortunate that I didn't have to put up with your company. For just this reason, the construction may occasionally be used to good effect in more formal contexts to invite the reader to take the point of view of the speaker or subject: The request seemed to her to be quite reasonable; it was so unfair of the manager to refuse.
