your car isn't going to tell you "hey when you come back i'm gonna be broke" shit happens and when they break you wont expect it. I'm leaning towards the throw out bearing if its squealing. its not letting the clutch to engage or disengage. possibly your pressure plate also. how old is your clutch in it now? Does the pedal feel the same? if it does its probably not your slave cylinder. just some things to rack your brain with.
