about stopping Abilify suddenly.

I am concerned by your post. It does not say you are here with the approval of your parents. And it implies you stopped your Abilify without their consent.

This drug is very sophisticated. It affects many receptors in the brain, and like other drugs for mental illness, can cause a serious change in the way your brain works. Sudden removal of drugs then cause a "withdrawal" syndrome because all of the receptors have to adjust to the changes.

Psychiatric drugs typically are tapered off, to prevent reactions.
Your reactions have been documented on the net a bit.
But because Abilify is relatively new, and just now becoming more widespread and popular, the issues of discontinuing are just emerging.

I hope you consult your doctor ASAP and discuss your concerns with this drug. Then if you choose to stop using it, you will safely taper off of it.
