People who don’t want to face their own responsibility for problems often look for someone else to blame. I’m so, so sorry that members of your family expected an 11-year-old to do what the adults couldn’t do to fix the marriage. That is so unreasonable. If you question that, take a look at 11-year-olds that you know and ask yourself if you would expect them to be a marriage counselor for angry adults. It’s ridiculous.
But, being only 11, you did what 11-year-olds do. You took the responsibility seriously and then felt like a failure for not being able to do the impossible. I hope that now that you are older, you can have sympathy for the 11-year-old who still lives in your memory and remind yourself that there was no way that your could have repaired your parents marriage when you were only a child. For that matter, you can’t do it now either!
Your mother is not a happy person. She will not be happier if you commit suicide. It will only give her another reason to hold onto her idea that she is a victim.
I’m very glad you wrote. It is a good first step to separating from your family’s unreasonable expectations and for claiming yourself.
