Heartburn is killin please help 😩

Am currently 32 weeks pregnant and have heart burn that doesnt seem to want to go away. Lets put it this way it makes me not want to eat and i can barely drink water because it always comes right back up. The burning factor takes my breathe away and makes it hard to breath. I want to give up!  Its like a punch to the chest everytime. Ive tired apple cider vinager with water to calm the acid but nothing is helping!! And not to mention (tmi) am getting diarrhea now too 😩 someone have advice or go thru this too? Idk if i can makeit or take it much longer.. Am getting really weak and dizzy from all this
