My heart is beating fast just reading this.
I got pregnant at 21, the dad and I had been together 2 weeks for what we thought was a quick rebound fling, he was still married (but separated) to his ex, I worked 40 hours a week, but in a temp job so of course I stopped getting offered work and ended up sleeping on my mum's sofa. I got such bad morning sickness that I started weeing blood, and for the first six months I probably went out of the house about 10 times. The baby was born prematurely, probably because she wasn't getting enough nutrients.
While stuck at my mums house, I could only manage to go online, where I would find horrible abusive messages from so called "friends", telling me that I should be ashamed of myself for having an unplanned pregnancy, that I shouldn't dare to show my face or share any baby news online as people might see and be offended. Mutual acquaintances still act like this was some kind of argument between equals and not two or three professional women in their forties bullying a vulnerable 21 year old.
People who actually honestly seemed to think they were my friends would tell me that there was no way that they would ever "allow" themselves to get pregnant (I literally had unprotected sex once - I was always the most careful of my friends and had only one boyfriend before this, and my friends wouldn't even carry condoms in their handbags when meeting up with men that they intended to sleep with)
Once the baby was born, I started hearing voices and seeing the bullies everywhere, I would be too scared to go anywhere and I was petrified of hurting my baby because everyone had said I would be a bad mother. I was so ill that I ended up in mental hospital several times.
Why did people feel the need to be so horrible? It was an awful situation and I was petrified, and when I tried to be happy about my baby, everyone would shoot me down.
But, still, I suppose I can spell and I read the Guardian, so that's ok 
DD1 is 5 now, and she (and her 2yo little sister) are the absolute focus of my life. We are pretty poor, but the kids spend loads of time outdoors, DD1 is a very fluent reader, DD2 knows most of her letters, they have a loving family, they both talk so clearly and with such a large vocabulary for their ages that people are amazed. I am happily married to their Dad. Not that any of that should matter.
