Re: what should I do...?
Weaning typically involves slowing reducing the amount of times each day that the breast is emptied. So, you could try moving from three pumping sessions at work to two more in the middle of the day, then one in the middle of the day, then none. However, it looks like you're a teacher, so those breaks probably aren't very flexible. In that case, turning off the pump before you are totally empty will gradually tell your body to make less milk. Eventually, you'll be able to skip one session, but will still be full enough to need to pump at the next time. Then slowly lower the time spent pumping at that session.
If at any time you feel overly engorged or painful, then weaning is going too fast for your body.
