Question about feeding and engorgment?

My son is almost 2 weeks old and I exclusively feed him... I have to pump every time he gets done eating and also in between his feedings and he eats every 3 hours. Because if I don't I get so engorged that it makes me wanna cry. When will that go away? and also Im having a hard time keeping him awake to eat. He will only do about 5-7 minutes on each and it drives me crazy. I hate having to pump all the time. I feel like I have my out all the time. And as of right now I have 57 bottles in my freezer of milk, and each time I pump I get between 3-5 ounces. I don't know what Im gonna do with all them because I really don't want him taking a bottle but don't want them to go to waste...I just feel like there is something wrong
