Need relationship advice

So today my fiancé who on july 3 we will be engaged for a year n together fully for a year n 10 months but its getting harder. He doesnt talk to me or let me talk. I truelly love this guy. But i been trying to talk about my health issues n i said my blood sugars are not good n he just asked if i was bedridden or if i was unable to function as a full human being. I said no n he said then you are fine im not going to worry about it then. He knows i have depression but he feels like i can just turn it off n function like a regular person. I dont know if my relationship is healthy anymore. Any ideas that could help save my relationship or should i throw in the towel. I really want to save it
