Hi there.
Don't try to work this out by yourself. Your being on this site already indicates that you do want to seek out help.
Yes, it's pretty normal for you to feel that way. It takes a while before we can live with the reality that we're given by God. When I went through an abortion, I didn't think much of it. It was only until my wfie and I lost a baby after having fed, clothed, bathed and put him to sleep for five months that the reality of having lost two babies really hit us. It was a while before I could really move from this. What really solidified everything was the birth of a daughter a couple of years later and yet another daugther a year after that.
You need to talk to someone definitely. It doesn't even need to be someone who went through that though there are people here who have. This is an experience that necessitates the true healing power of the love of people who really do care for you. Don't sell them short by keeping them out of your life. Don't sell yourself short either. They were given to you for a reason and this is one of those reasons.
Lastly, take heart that the mere fact that you're still alive indicates one thing: God cares for you and is holding you in the loving palm of His hand. Take heed and get strength from that. He's taking care of your babies and there's no one better to care for them.
There are cases sometimes that we are utterly powerless to prevent the hurt of our loved ones and sometimes we even take an active part in their pain. In cases like those, I believe that God comes in to make sure that the care we cannot give is given a hundrefold to those who deserve it -- our babies, in this case.
Take care, honey. You owe it to your babies. They won't like it one bit if their mommy is in pain.
