Relationship Problems

This past October my husband and I had our 4 year wedding anniversary and our 7 year anniversary of being together. The past 3 year or so I have been dealing with mental health and women health issues. Over the last year my husband has begun to constantly take jabs at me. Telling me things like “oh knowing you you’ll never finish that” or blaming me for literally everything. He’s very oblivious to it and tells me to get over myself when I stand up for myself or get mad about it. It has continued to take a toll on my mental state of mind but it scares me to walk away from him I don’t know what to do at this point. Please help.
