I gave birth 6 months ago and am breastfeeding. does any of these contribute to me having no sex drive at all? is it hormones or just me?

Aside from the dryness, there are also the fears of having another baby again right away (especially for first time moms) and of pain (especially for normal delivery). There's also exhaustion from taking care of the baby and the general lack of sleep. I've found that on bad sleep days, I can't even get excited about ANYTHING (not even ice cream or a great movie).
