Goodness, you poor thing, that does sound particularly traumatic, I'm guessing you had a surgical aspiration with a cervical local anaesthetic?
Had you opted for a general but they couldn't perform it due to the fact you'd had liquids before the procedure? That does seem particularly harsh, were you offered any sedatives before the procedure?
I had a medical abortion through the NHS years ago at which the nurse attending to me was particularly insensitive (she showed me the scan before the procedure and asked me if I was certain I wanted to go ahead, if I hadn't been so upset by the whole experience I would have reported her), I was so scared of seeing what I'd seen on the scan I just couldn't relax and let it happen and ended up up my back with the nurse manually removing the products of the pregnancy with forceps.
Horrible.
BUT, I did get over it, I was shaken up for a good time, but deep down I knew it had been the right decision, as it sounds ads though it was for you, no matter how horrible the process turned out to be, you did the right thing for you at the time.
It's a good thing you have your partner to support you, you're clearly quite traumatised by the whole thing. I would suggest taking it easy for a while, let him look after you until you're feeling physically stronger and your hormones have settled down, then if you're still feeling upset about the experience maybe seek some counselling to help you process what happened.
You will start to feel better though, I promise you that.
