I think I have anxiety and depression. It has manifested an extreme distrust for others

My husband and I are in a terrible place. Part of me wants to fix it, but then I'm caught up with not knowing how and not being able to communicate my feelings to him because he always feels I'm blaming him. Sometimes I am because the feelings of distrust are so strong. I feel they must be coming from something he's doing, but sometimes I know I'm being irrational. Still, that doesn't stop the anxiety. The other half of the time, I just want to walk away, but I feel like that will only be a temporary fix.
