Postpartum hormones

I'm almost 2 months pp with my second baby, is anyone else dealing with some really upsy-downsy emotions and anxiety? It's partly due to sleep deprivation, that's for sure, but I'm otherwise feeling anxious about a lot of things and my brain feels like a giant bowl of mush. I hope I start feeling back to normal soon. I don't think I have PPD, I just have a little anxiety and I need some sleep and exercise and my memory is crap.
