Are you really getting this wound up when you only applied in December?Nothing. Which is unfortunately normal. Most of the time one’s application takes to process is actually spent in the queue where there is absolutely nothing being done on your application. Its just parked until an officer picks it up again.
Anything less than six months is pretty darn good. While I understand everyone wants it to go quickly, at this stage you're stressing yourself out for no reason.
Put down the computer and go outside for a bit.
