exit code 0... not really

So for the last couple of months every time I try to start up any version of minecraft the loading bar will make it almost to the end but then stop, after a few minutes of waiting then it says Java(TM) SE Binary is not responding, if I click wait for program to respond ill sit there for hours and nothing happens, The day before this happened I was building a really cool castle and I logged off for the day, when I decided to get back on It would not let me ever launch minecraft, every time I clicked close program it would launch the launcher and say exit code 0, I looked up and watched many videos how to fix this and none of them worked. Please help.
