I think that you are already in the process of moving towards happiness again.
One thing that might help you is to understand that often times the first prescription of medication to treat bipolar doesn't get it 100% right. In other words, working with your psychiatrist on an ongoing basis will help him or her to determine what is the best course of medication treatment. This doesn't mean that you're not on the right medications, but if you're not feeling as well as you deserve to feel, this would be a good conversation for you to have with your doctor. Remember, it often takes almost 10 years to get the right diagnosis, and now you are able to get treatment.
I think it would also be helpful for your husband to go with you to a consultation with your psychiatrist. There are some wonderful books and blogs that will help you and your family to better understand and treat your symptoms.
