Well, I'm not sure there's really enough info for someone else (here, anyway) to make a judgment about this for you. That said, I notice that you don't talk about how much you love speech and wish you could do it, and you are not choosing a different but similar profession - that tells me that maybe it's not worth it to you personally to keep trying.
I really want to do this job, and I have a good background and good grades. But getting into grad school is so ridiculously competitive that good -- even great -- is not good enough. I'm seriously reconsidering because even though I love the field, I think I can be happy enough doing something else (like SLPA).
And while I'm at it, I'm not terribly impressed with these grad schools. They all seem to be disorganized, poor at communication, and so full of themselves. They CAN be, because we are all dying to get in and must put up with their crap. And honestly, I can see no reason why a master's is even necessary for most SLP jobs. Medical, sure - why not make that a master's job? But I am perfectly capable of reading test directions out loud and counting check marks, which is pretty much the only thing that separates an SLPA from an SLP.
Sorry for the rant. Obviously I am bitter as well.
