An interesting article from Dennis Prager, author of Happiness is a Serious Problem: http://www.townhall.com/columnists/DennisPrager/2008/03/11/why_are_so_many_women_depressed_part_i
I know moms who have taken antidepressents and those who haven’t. So, I don’t think there’s one right answer for everyone. The trouble is figuring out what the right decision is for you personally. For sure, I would recommend counseling first. General practioners are too quick to write out a prescription without being able to diagnose whether there is a problem and what might be the best solution. Biblical counseling (but be discerning because just because the counselor is a Christian doesn’t mean he/she is providing Christian/Biblical counseling) can get to the heart of the issue and refer you to a pschologist if a serious depression is diagnosed or if medication would help you get back on the right track. And don’t forget, it’s okay to have ups and downs. People, especially women, think they have to be “up” all the time and that is an unrealistic expectation. Pray God would satsfy you and ask Him to replace the sadness in your heart with joy.
“Satisfy us in the morning with your unfailing love, that we may sing for joy and be glad all our days.” Psalm 90:14
