Sleepless you need to get a grip.
What you are saying makes no sense. If you are thinking about terminating because of guilt that you may have damaged your baby despite massive evidence to the contrary, how are you going to live with the knowledge that you had an abortion, should you go ahead?
I terminated a pregnancy in circumstances different to yours. It was the correct decision, but doing it changed me fundamentally as a person. It was a shift as profound as loss of faith. It changed the way I see the world and my place in it. The guilt still affects me over a decade later.
A termination is not a solution. It will not be the end of the problem. It is one course of action you could take, and to have one in your circumstances takes you into a future where you may well feel a whole lot worse than you do now.
To have a termination to get rid of feelings of guilt makes no sense at all. It will almost certainly make you feel more guilty, more than you can possibly imagine at this time.
The other course of action is to take steps to protect your baby from your anxieties. If you continue with the pregnancy and have the baby, i promise you there is a future where you can move on from these fears. The baby will arrive, all will be fine and you will have other more immediate concerns to think about, such as looking after and loving your amazing baby, and the feelings of guilt you have now will quickly fade into the past.
If you have a termination I am worried for you that those feeling of guilt will not fade into the past. Instead you could be effectively turning them into a millstone around your neck that you will carry with you into the future. Please don't do that to yourself.
It's great that you have started talking to people. Please keep talking to them, and to us.
