How do I communicate to my partner that I have anxiety?

We recently had a disagreement. He told me something and I made a big deal about it and now i don't know how to solve the problem because he's not talking to me anymore. I sent him a text where i explained that i have anxiety that makes me overthing and overreact on things but he ignored me. I also apologized but nothing changed. It has been a week since the argument happened and he hasn't talked to me yet. I tried to text him but his answers were cold and distant.

What to do?
