I was when I actually thought that hard work, diligence and intelligence would get me somewhere You are the person you think you are. Perhaps you could use this floating as an opportunity to re-evaluate your options. Research what you can/could/want to do might be way to recapture your motivation and energy. I wonder if you could start with a list, get your husband to help, or ask friends what they see you as doing. Much you will discount but some will give you hope. If your husband buys into what you want to do, as he did not over the PhD he may be more supportive. Good luck.
