Minecraft wont start

I haven't opened Minecraft in 3 days, then I just out of the blue decide to play the game, but it wont open. I decided to see the task manager, and after clicking Minecraft.exe several times, i see 3 Minecraft.exe processes and a lot of java and javaw.exe proccesses barely taking memory there, most of them lying at the bottom of the task manager list. I tried to uninstall all my java versions and I couldn't because it said to "Save work and Data" for the multiple java and minecraft.exe processes there, but I couldn't at least even kill them. I honestly don't know what to do.
