Everytime I get on Minecraft it shows to play offline then when I get on MULTIPLAYER it shows my servers just pinging then I get on SINGLEPLAYER and click on one of my worlds it crashes.

1.I get on Minecraft says play offline.
2.I get on MULTIPLAYER and its just pinging
3.I get on SINGLEPLAYER and I click on one of my worlds and it crashes.
I forgot when I get on the lancher it shows a lot more stuff than its suppose to.
