HI K.,
I'm glad you reached out for support, because it is hard for most people to understand your feelings - most just think you should be happy everything turned out ok. My first child was born at 29 weeks and spent 67 days in the NICU before he came home, also on oxygen. I have since been pregnant three more times, each with very different outcomes, some happy, some not.
It took me a long time to understand my emotions after my preemie's birth -- here's what I figured out:
Although your baby is healthy and home with you, you still lost your pregnancy and completed only part of the journey that is so very important to becoming a mother (esp. if this is your first child). You probably had a vision of what it would be like (baby showers, registering for gifts, decorating a nursery, having maternity photos taken, etc.), and you lost it all, likely with very little warning. People have no idea what it is like to be pregnant one day, with no baby supplies in the house, no rites of passage like showers behind you, and then BOOM! the next day you have a baby struggling to survive, and you are off and running in your new life.
Although people mean well when they tell you you should be happy your baby is ok, they don't understand that you must first grieve the loss of your pregnancy and of your ideal vision of what it was going to be like. It is a VERY significant loss! It doesn't mean the world is over, and it doesn't mean or that you don't count your blessings, or that you are putting your loss at the same level as women who have lost their babies; it means it is a significant loss, followed by trauma, fear, stress, and anxiety. This massive upheaval in your life needs to be acknowledged and processed before you can accept that your journey into motherhood changed so dramatically with little or no warning, and no control. This is important, , esp. if this is your first child, because your journey into parenthood might differ dramatically in some ways from parents of normal, healthy full term infants. You will adjust and it will become normal for you, but it will take time to accept the hand that was dealt you.
For me, the negative emotions I experienced -- even after taking home my healthy baby -- slowly chipped away, and I slowly became more consumed by parenthood than by the journey that led me there. However, there was one big piece that I really struggled with: the really strong desire to try to do it again, this time "right." This was terrifying because no one could guarantee that the same thing wouldn't happen again. Indeed, my next two pregnancies led to even more grief. I tried one last time, and was rewarded with a perfectly normal, 39 week pregnancy and a boisterous baby boy. Now I look at both my boys - the one born at 2lbs and the other at 7lbs. , and I think, "My God, you are both my miracle boys". I was finally able to bring closure to all of the loss and yearning I have felt for years. I know I am extremely blessed, and that things could have turned out very differently.
Please don't interpret my experiences as a solution ("just keep trying till you have a normal pregnancy!"). For many women this is not desireable or possible, and thus other means are necessary to reach closure. Still other women won't react as I did while adjusting to a preemie birth. I just wanted to let you know that the things you are feeling are very normal and understandable, and you are not the only one feeling this way. If you would like to talk about your current feelings, and about your life with a preemie, please send me a message and we will be in touch. Hang in there and be kind to yourself!
