Drying up milk??

I’m done breastfeeding and am wondering what are ways to help dry up my milk? I’m not producing like I need to and I’ve tried everything to try and change it.. my body just isn’t cooperating. I’m only getting half an ounce from both breasts combined. I’m scared of getting mastitis. So what can help me? And please no judgement for the decision I’m making. I’ve already had enough of it from this group. I just need some help from mommies who have weened a child from breastfeeding before and had to do this. So for anyone with a negative comment or thinks they need to tell me I somehow didn’t try hard enough just please don’t.. remember fed is best. I feel like a big enough failure already.
