Postpartum anxiety

I’m 5 weeks postpartum and just within the last week or so I’ve started having a great deal of anxiety regarding my baby’s weight, sleep, everything. I worry that I’m not a good mom because I don’t always know what to do. Can’t get her to breastfeed. I’m also overly tired, my mind is always racing and I just overall feel anxious and worried inside.... my mind is flooded with thoughts. I’ve also started having anxiety about having postpartum psychosis.. I’m scared to death that I’m gonna get it or that I already have it and don’t know it.. if I had psychosis would I be aware of it? I’ve just opened up to my husband about this and read the symptoms to him so he could help me assess myself and he seems to think I have anxiety and that I’m overly tired... What do you guys think? I just need some support from other mamas.
