I’m very sorry for the loss of your dear child. I wish I could say something that could take away the grief, but I can’t. I’m afraid that empty place will always be with you. Even many years later, you’ll wonder what she would be like now. Little dates and times will trigger your memory, from now on. They will say it gets better over time, but I can attest, it simply gets more bearable. It will never go away, but I don’t think you really want it to.
As for your parents, I’m sure they love you and share your sorrow the best way they know how. My guess is they’ve never lost a child, so they probably just don’t know what to do. They may just know how to discipline and criticize. You could be the President of the United States and your still their baby girl. Probably the best thing to do with them, and everyone else, is just ‘let it go’.
If not, muster all the charity you have, and ask them what to do, being prepared to ask good, tough follow-up questions. For example, They say, ‘don’t have any more kids.’ Ask ‘Should we use contraception, or unilaterally deny our spouse their marital rights? What choice accepts God’s plan?’
Again, it’s probably better just to let it go, but they might ease up a bit if they could hear themselves giving their daughter advise that is absolutely contrary to the teachings of their own Church.
I don’t mean to help you pick a fight, but we’ve gotten the same treatment, and I know what it’s like. You can’t believe that your own parents will say some of the things they do.
Just keep doin’ what you’re doin’, following God’s plan.
