I personally don't think Sasha actually wrote the April Journal-not that way that it was presented I mean ie: The over the top announcement. I think she wanted her fans to know that she wasn't going pro-that she was staying eligible for the next 4 years (to keep her options open if nothing else) but she really didn't/doesn't know yet what her future holds-ergo the stuff about deciding how much she would compete next year later in that April journal. I also think that the fact that she can't just say she's skipping the GP with out at least threats of consequences may have played a part in her seemingly change of committment status. I think she isn't happy that it has to be all of nothing really for her next season and if she skips next season will she even be able to mentally get back into the game.
As for acting she seems to be enjoying the start of learning a new way to perform-that is what she loves to do. I also think that her talk of it's the process leading up to the big stuff (nationals, worlds, Olympics, ect..) probably goes with how she's looking at her new love as well. She may never get big but she is loving the idea of learning the craft.
