This is definitely a very big problem and is faced by almost all people,while withdrawing from anti depressants.
In fact you should have taken some more time in withdrawing,rather than stopping it abruptly.You could have kept on reducing the dose till one fourth of the 5 mg tablet.
Well in any case since you have stopped it completely you may wait for 2 to 4 weeks more to be out of it completely.
Take the following measures
Take enough rest and sleep properly
Take plenty of water and fresh juices
Take fruits and green vegetables
Avoid alcohol and caffeine
May take some ADVIL
In case the symptoms are severe,you may ask your doctor to prescribe some XANAX
to you for few days only.
