Massallah pertaining to talaaq

my intention was to scare my wife,thats why I gave only 1 talaaq,I never meant to divorce her completle
we are now married for 14 years and have 7 kids together.
I am a little worried and confused,are we living in haraam or not?
can you PLEASE advise me on the above as it is now causing me mental strain and anguish that perhaps i did the wrong thing.
PS. when I gave her the 1 talaaq,at that time I never meant to divorce her,just make her scared that she will become obedient and stop being stubborn.
