Hey guys

So I have been playing minecraft for a long time now, and I'm really addicted to it.
But today I have came across a problem, my game doesn't start up.

I press on Play.
The launcher closes and it goes to a blank page.
It reamains blank and sais that there is no reaction.
After that the fail log shows me this:

Completely ignored arguments: [--nativeLauncherVersion, 286]
[21:02:00] [Client thread/INFO]: Setting user: HelloImWeird
[21:02:00] [Client thread/INFO]: (Session ID is token:42d99955a6ee470f8e4306af82ec716b:3d3d9a4422404bbebd0f6fe1f5d007e8)
[21:02:02] [Client thread/INFO]: LWJGL Version: 2.9.4

What should I do?
This makes me wanna cry pls help senpai
