So sorry to hear you're not too good.
I had it with my DS who is now three - but it came back with a frigging vengeance after I had DD (15 months). This is my account - it's not nice and I'm so sorry if I offend
I remember calling my DH screaming that I was going to kill her. I had the pillow ready to smother her because she would NOT shut up crying. She'd cry all day...all night and in between. I would imagine my life without her and smile at the very thought. She was a massive mistake - the pregnancy was rough, the birth was agonising, and then there she was totally ruining our unit of three.
It just got worse and worse until I lost it well and truly. DH came home to find me in a heap on the kitchen floor with DS screaming in her car seat with her coat still on (I had tried to go out but never made it through the door)
He tended first to her and called the HV in the process. She came over in a heartbeat and took me to the child safeguarding team at the hospital where I was interviewed, assessed and kept overnight on the mental illness ward. I was prescribed all manner of drugs, counselling and CBT.
After that, I went home dazed confused and not entirely sure what the hell to do. Both sets of grandparents live abroad and no friends knew what was going on, so my DH had time off to help me - which was rubbish because he's self-employed so he didn't get paid.
Things got easier, but not for a long while. Everyday for two hours I had the safeguarding team round with a doctor to asses how I was coping with my daughter. I never felt so useless and worthless. This carried on until December last year when they were finally happy to sign me off.
Since then, I'm still taking medicine but I feel so much better. I have never loved my beautiful daughter so much in my life, and my love for her is getting stronger everyday. The thing is she wasn't a mistake - she was very much planned. I couldn't see past that and I can't think about it because mu thoughts back then towards her were just wrong, nasty and despicable. DH and I don't really talk about what happened - and I guess we should. The only thing he has ever said to me was that he had never, ever seen me looking so empty which broke my heart. I put him through so much too and I forget that a lot.
There is light at the end of the tunnel - it's long and bumpy but with the right support, medication or counselling or whatever treatment you decide is best you will beat this crappy illness. I would swear but I've forgotten how to do it on here!
