Please read!I need advice

So I have posted on here a lot about my breastfeeding troubles, and my son (8 months old) refusing a bottle. Now we are having more problems with breastfeeding. My supply has suddenly dropped drastically. I don’t know if it’s because my diet has changed, but my son still won’t take a bottle or a sippy cup (or even a regular cup). I had to syringe feed him this morning because my boobs are as dry as a desert. As soon as he realized what I was doing he fought the syringe out of my hand and would hit it away anytime I tried to bring it to his mouth. He is hungry and I don’t know what to do. I tried to hand express to see if anything would come out and I only got a few drops out. I’ve tried every method there is on google to get him to take a bottle or cup (I’ve left him with dad for a few hours, tried to feed him outside, tried walking around and patting his bum, tried sitting him in his high chair, cold milk, warm milk, and about 20 different bottles and cups) and still no luck. I’m getting very concerned. Besides this, he is an extremely happy loving active boy. If anyone has advice please share.
