Is it possible to get delayed postpartum?

I have had postpartum anxiety since my baby was born, now 12 months old... in the last 4 months sleep deprivation has upped itself. Waking every hour most nights.

I was in tears last night. I just can’t go on. I have had suicidal thoughts. I have always been there for my baby but can’t help but feel depressed and suicidal about my life and not being able to cope and go on. Everything is getting on top of me😭 I worked 3 days a week, no family around, struggling to pay for childcare and our home is a mess. I can’t keep on top of it all. I can’t do this anymore.
