ok so i decided to try and figure out what it was that i'd pressed accidentally so i went across my keyboard pressing each key and number in an act of desperation. As soon as i hit 'b' on the keyboard everything was fine and dandy again
Haven't a clue what 'b' is the shortcut for though, still, it fixed the problem.
Hopefully this will help those who are also having the same problem.
