Bless you. I'm so sorry. I had exactly the same experience, so I can tell you the journey I've been through, and try to help you.
The hormonal shock is very strong, and this in turn intensifies the emotions you feel. I was the same - just woke up and cried. Cried for six weeks non stop. Had to give up my job as a trainee journalist. Nothing felt significant or worth doing, apart from what I felt I had lost. My bewilderment and self-recrimination were totally debilitating. I just sobbed.
The horrified realisation I had was that while everyone had told me my life would be ruined if I had the baby, in fact it was ruined by the grief of not having her.
But: you will gradually return to yourself. You will make peace with yourself and what has happened. I went away to an island for a year. Nature helped kind of soothe me. But I really should have had counselling. Nowadays post-abortion trauma is very much a recognised response that some women experience, and it is not just feeling sad for a while then bouncing back - it is really severe and it can, as you say, just stop you functioning. So I would say you really must go to your GP and/or find online a specialist counsellor and go to see them. I'm sure this way you will heal much quicker and better than I did.!
I ultimately have found the best peace I can by listening to my heart and understanding that my child would not want her mummy to cry. I actually went back this summer to the beautiful island I'd been to just after. And I confronted myself and said ok, what would she say to you? And it would only be don't cry, Mummy. It's ok. Smile again. Please.
You went through with this because you thought it was the best and most sensible choice. For your child and for you. You can only do your best, and that's what you did.
You will get over this. And much quicker and easier with counselling.
Go easy on yourself. This is a natural process and in time the feelings will subside and fade. 💐
