Depression a difficult challenge. If you are not currently under treatment I encourage you to do so. From your description it sounds like your husband also could benefit from some professional care. The garbage is a symptom of motivation not ability to manage it or mow the grass etc., you both have needs. Please consider calling or going to VIM, Volunteers in Medicine, I believe their services are essentially free. You can do this, plus it must feel depressing coming home to this "mess" each time you pull in the drive-way. You deserve better.
