2 weeks PP and oversupply

I just don't know what to do.. LO is only 16 days old and I've been EP since day 2 in the hospital. I have a medela pump in style.. My milk came in on day 3 or 4 and I got SO engorged. I'm not joking, I looked like dolly parton. My breasts (which normally barely make it into a B cup) were HUGE and swollen almost to my collar bone and under my arms, and red and shiny, hard like granite.. it was awful and it lasted about 5 days before the lactation consultant told me to just pump off all the milk. It took 2 1/2 hours and I got 10 oz out of them at that time.

Then I started pumping every 4 hours for 20 minutes and was getting just a little extra milk. Now I'm getting about 7-8 ounces (combined) per pumping session (42 oz a day!) so I'm freezing a lot of milk. LO only eats about 20oz a day..

The problem is that carrying all of this extra milk HURTS. I pump it off and within a few hours they are back to hurting and start to get hard and engorged. They leak all the time and when let down happens they actually squirt. I don't know how to reduce my supply?? I am currently pumping every 4 hours for about 10 minutes and then I stop because I am terrified that if I keep pumping and taking off more milk I will just start making even more milk and the problem will get worse.

This is causing me so much anxiety and fear, I can hardly think of anything else. I cry about it
