P.M.
I'm sorry you're feeling so much pain, C.. It takes time to make peace with any deep loss, and a hoped-for baby would be high on that list. I hope you succeed in having the pregnancy and baby you want some day soon.
I hope you'll bear in mind that people make thoughtless comments – that's just what we do, and what you probably have done, as well, without intending hurt. I wonder sometimes how many people have taken offense at my own dunderheaded statements. Just seeing you or me walking around might bring pain to someone who can't walk. There's no getting past that.
There are also people who will intentionally hurt others. They are not worth spending our emotional energy on. If we feel bad, then they win. We don't have to allow that. With a little practice, I've learned to actually feel a touch of pity for such folks.
What you might try to do is find a spark of joy for those around you who are pregnant or new mothers. Give them this lovely gift, which you will want to receive from them in turn when you do become pregnant and give birth. Can you stand briefly in their shoes and consider how hard it would be if you knew your pregnancy was causing someone else pain or resentment?
Many wise thinkers have noted that our happiness or misery does not lie in things or events themselves, but rather the way we interpret or think about those things and events. I've found in my own life that this is true. So, if you really want to move past your pain, forgive yourself, your body, your baby, and other pregnant women for the way things are. Keep trying to conceive, keep finding positive outlets for your feelings (counseling or a grief support group might be really helpful), and do something positive and loving for others every day.
My best to you.
