Help a mama out, please. LONGISH POST

A bit of a background:

My baby boy is now 3 months 13 days old and my maturnity leave is close to an end. I go back to work on the 23rd of October. Now my dilema is, i work in a different city from where my moms resides and I'm leaving him behind to stay with my amazing mothers. Reasons: (community, environmental and caregiver absence while at work). In all i have to stop breast feeding 😢. Luckily i have introduced powdered milk to my son at 2 months (only when i went for errands without him) so he is used to it and loves it.

Now my problem is I have stopped breast feeding yesterday and my breasts are heavy and sore. Can anyone help as to what to do, home remedies.
