That hole is called a scar. Unfortunately, It will not go away; at least not soon. Do touch it and don't play with it, the hole will get smaller. If it is very big, it may still be visible after it heals which can take years.

If you have a lot of acne, you should visit a dermatologist. They will definetely be able to help you there.

Disregarding everything I just said, I heart that clensers with a certain ingredient will help the skin repair it self. Forgot what the ingredient was, but it is in Etival products. I never tried tho.

Oooh, I've been there. The best thing for your skin is to let it heal normally. Don't poke it or pick at it any more! You can try putting medicated cream on it to help the healing. If you don't mind makeup, you can try covering it but that will slow down the healing. Sorry man, but I suggest leaving it alone and facing the sharks on Monday. :-(

Don't pick at it anymore, sometimes you can get permanent scarring
