I would look at different pills. Maybe you could get a lower dose, one that would still protect you against pregnancy but doesn't have as strong other side effects? There are tons of different brands, and there's also the option of "mini pills" that have no estrogen in them. Talk to your doctor, tell them you enjoy the pregnancy prevention but the emotional side effects are keeping you from enjoying your life.
At the end of the day, if every pill prevents you from being really happy, I would suggest going off the pills and using some other kind of pregnancy prevention. If you don't want children for many years, you could use a non-hormonal copper IUD. If you're done having children, you could get your tubes tied or your husband could get a vasectomy. It seems he should be willing to step up a little to ensure you don't get pregnant as well!
