Hi R.,
I'm no doctor, but I can see how either hormones or the anxiety meds might be making your sex drive low. I know there is like one week out of each month, due to hormones , that I want sex all the time, and the rest of the month I'm like, whatever.(and my husband thinks I'm a nympho, lol)
Talk to your doctor about the meds, see if that is causing it. I know some friends that have tried the natural approach to anxiety and depression with 5-HTP.
I have three kids, used to be very sexual, now it's like 1-2 a mos, which makes me crazy, but doesnt' seem to affect my husband as much. Our problem is we are not very good or strict at getting our children to bed before midnight or later sometimes. I swear they are machines that can run on empty, I"ve even talked to the doctor about it, he just laughs. My kids are 16,11, and almost 4.
Enjoy each other when you can, and remember, kids can make your sex life very rare, lol, specially with the exhaustion of not sleeping like you used to before you had kids too.
Take care, all will work out.
