im not sure if we can be together

I have sever anxiety me and my fiance been together two years known eachother for four and during our argument he voiced how tired of it he is ive always just dealt with it medication made it worse. When i voiced to him why i was so upset yesterday his response was im tired of this shit you can control that shit stop using that bs as an excuse. I was furious and hurt and told him to go. Like if i cant get him to understand what i go through idk what else to do because just stopping my anxiety hasnt seemed possible
