Minecraft wont load worlds or servers. HELP!

I will start off by saying my computer is more than capable of running Minecraft. I got 1000+FPS with Optifine before this issue started happening.These issues started once I tried to install forge. I have completely removed forge and now I am just trying to get vanilla to work. When I attempt to load any world or server on any version of Minecraft it does not work. Worlds sit at the "Loading world, Building terrain" and the window wont close until I force close the program and servers freeze as soon as I load in the world. I have tried completely removing Minecraft from my system and Java and reinstalling them and that does not fix the issue. I have found little help online for this issue. Here are the logs from the attempts at loading a world:

It sits at this for as long as I let it.
