my car just won't start and be careful because you never know when its going to go

The problem is it was really cold outside and i had got inside my car.. when i put in the key and turn it to start it, it didn;t respond so i tried again and it didn;t start the third time i tried it, the engine gave out a really weird sound. Than when i tried to switch gears it couldn;t move it was stuck... also i couldn;t turn the car off either... it really sucked.. and i still can;t get anyone to fix it yet
