Hello, cooper. Yes, depression and anxiety are difficult to deal with. My thought is to tell the psychiatrist the treatment is not working. Even the strongest need help sometimes. Your husband needs to get his medications adjusted or changed. He likely would benefit from therapy too. He has self-esteem issues that need addressing.
Has your husband been tested for learning disabilities? I think he should be if not. He might want to ask the psychiatrist or therapist if it is a good idea for your husband to tell his employer he cannot read or write. Who knows, the company may help him learn or make other accommodations. Also, the professionals may have some ideas to help him learn. Tennessee has this program:

You need to take care of yourself too. I think it is important for you to attend some therapy sessions with your husband if he is in therapy. If you can, you might talk about how your husband's problems are affecting you and what you may do to help him.
