Hormones? Breastfeeding? Sleep deprived? PPD/PPA?

Most days, I feel like I have no energy, very weak, & sometimes a little dizzy. Basically I feel like I just want to lay down all the time (which is impossible while taking care of an almost 9 month old) & don’t feel well. Im also still breastfeeding.

I push through how I feel but I’ve been dealing with it for about 6 months now, good days & bad days. Anyone else have anything similar?
