Op,
Im admitting my deepest darkest secret on a public forum in the hope it will help you,even if it gives you a modicum of hope it will be worth it...
I remember being where you are.
Except i decided i would kill my ds as he has SN & i couldn't bare the thought of him going into care. I was terrified of seeing him dead so i worked out how to do it so we both would die but i wouldn't actually see ds dead.
I was paranoid, thought ss was following me&watching my house.
I used to leave ds in house on his own,he was about 6 months old at the time.
I spent thousands of pounds on clothes. My Dd was 3 at the time,I would cry all day,i never took that poor child anywhere other then to drop her to nursery. I often wonder if she can remember this time,she's got a funny sort of personality,i can't help but think i contributed to it.
My dp had no idea any of this was going on. He would tell you i moaned alot or was miserable. Though i tried to talk to him.
Eventually i went to my G.P. I was prescribed AD. I spent 2yrs on them. I had a shitty H.V. She never got involved. I never took ds to clinic,only to G.P for jabs. No one else was involved,you sound like me. Even now the thought of taking help from outsiders is unthinkable.
I got better,at the time I didn't realise how ill i was. I have never spoken to anyone about having PND-this is the 1st time I've admitted how ill i was...7 years later.
When i read your posts it reminded me of the hideous isolation,dark,long scary days. So i might have posted this in vain but please go&see your G.p- how u feel is treatable. You sound, like how i felt. U& your dc deserve a decent quality of life&with a little help,its possible.
Take care of yourself.
