Postpartum psychosis?

I’m six months postpartum. I’ve known I’ve had postpartum depression/anxiety since 3 weeks postpartum but I guess was in denial at the time and I didn’t bring it up at my six week check up. Then I lost my insurance and didn’t have the money to go to the dr, still don’t really. I feel better over all though don’t get me wrong I still have bad days.. anyway my point is, about three weeks ago it was around 8am and I was rocking my son back to sleep, I was tired of course and had my eyes closed and heard a woman whisper my name. It sounded like my mom and came from the bedroom door but when I opened my eyes the door was closed and I thought to myself well if someone was here the dog would have barked because he always does when someone pulls in the driveway. Well then about a week later I was almost asleep and could have swore I heard the back door open so I got up and it wasn’t. Then last night at 2am I was awoken out of sleep hearing a man say will do, it sounded like it came from the baby monitor. My husband was asleep and it didn’t sound like my husbands voice anyway. No one else was in the house my son is only six months old so obviously it wasn’t him. I know no one on here can diagnose me but if you had postpartum psychosis what was it like for you? I thought you heard voices telling you to hurt yourself or baby. Am I literally just going crazy? Are these “delusions”? Are they symptoms of postpartum psychosis? I’ve never had anything like this happen before.

I currently still am depressed/anxious. I have good days and bad days... highs and lows? I suffer from insomnia. My son sleeps 12 hours at night but the most I get is 7 no matter what time I lay down.
