To Valda, I would say: If by "really" you mean "majorly; very very much; in a big way", then use очень. Or, if you get tired of using очень, you can say дюже, which literally means something like "robustly", and is comparable to English "majorly".

But if you mean "really" in the sense of "in reality; honest and for true; seriously; I'm not joking", then use на самом деле or действительно.
