boyfriend getting mad over my anxiety

I’ve recently took on extreme anxiety after my dog died last month. This past week I’ve now had panic attacks that are making me feel and act not the best. My boyfriend told me that I am very hard to handle and that he is not my caregiver. He also said I make him feel sick and that he doesn’t like being around me when I have anxiety. I’ve been there for him at times where he’s had bad anxiety and never once made him feel bad. We haven’t talked since last night and i’m not sure if I should write to him or not. I love him but I’m not sure if he wants to be with me or not anymore. Now my anxiety has gotten worse and I’m not sure what I should do. Any advice would help.
