Stop using MR completely. Stay away from it. It really makes the waiting period harder. Look how we all have been so excited and then disappointed coz of apple store going down and then getting no announcements et all. And since you need a Mac desperately, you`ll feel far worse than those of us who dont really need a Merom MBP right now but will buy it if they like it when it comes out. Just stay away from MR. ONly check the Apple store once or twice a day to see if there is an update.
Also consider what miles01110 suggested. It`ll help.
There is no point in getting a yonah MBP now. You have no option but to wait. All you can do is make your waiting period less painful by not visiting rumor sites every now n then.
