Unfortunately these symptoms you are describing effect a lot of pregnant women, so don't feel down on yourself... You are pregnant, don't stress out (or at least try not to). As for work, maybe try taking to your boss and seeing what he or she might be able to accommodate for you... And I don't mean to be rude but if your husband doesn't understand and gets mad that you can't do much about your symptoms and worries about money, maybe he can take on another job. You need to be in the best health for both you and the little one. But ask the boss about any accommodations or advice, or ask the doctor what you could do.
Anything you can do in what sense. Involving your job, helping your symptoms?
