Minecraft is crashing helpppppp.

So what happens is that I open the launcher, now my launcher needs an update (I cant figure out how to restart my launcher) I click play, its pretty normal until the tab with the crafting table opens thus loading for 10 seconds then saying Minecraft Not responding, it loads for forever then once you shut it out it opens the launcher back up and says that there was a game crash, this has been happening the past 4 months WTF do I do? Also as soon as it gets to the crafting table tab it now wont let me open it.
