I have been having serious problems with galactorrhea

My name is wendy and for the past two years I have been having serious problems with galactorrea. My breast are very sowlen because they are very full of milk and I have to express my breasts alot of or eles they start to hurt. When I express my milk the milk a bunch of streams of milk shoot every where so I have to express my milk in a big mesureing cup. It takes hours before my milk is done flowing and my milk reaches about three cups in the mesuring cup. My nipples often leak alot so I have to wear lots of nursing pads and I have to change them alot about six per hour. When I go out any where I bring a empty water becuase usually I when I have to milk nipples I go to a bathroom and milk my nipples. I've done tests to see if Im pregnet and all those tests are nagitive. All my friends and family know about it it's no secret. One of the brigtht sides is that I get money donating the milk or I keep the milk and make icecream out of it or I just drink it because breast tastes better and sweeter then ragular milk so I don't want get rid complety. I just want to reduce it. I also have a pitcher to prove my point.
