Kat, I have heard of this happening to another woman friend. She is full of rage at her mother for allowing her to be isolated off from the family and abused like this, even if the mom didn't fully witness the sexual abuse part, she had to know of the rest and what led up to it.
Were you the only one who was abused or were siblings abused also?
By isolating yourself, you are living out-continuing the isolation to yourself, so that is something you can work on. Isolation is itself punishing. You never, and no child ever, deserves any of what you were given. None of it. In fact, we all have a birthright, I believe, to be treated like the wonderful spirits we are, here having a human life. If we all treated ourselves with the love we deserve, and gave it out to others all of the time, being here would be entirely different and would shift "reality" in a huge way.
Buddhism says "Life IS suffering" and that is our reality. When I look at life, I can't disagree, but we must not accept suffering as inevitable. We must exist in a state of love that was NOT given or experienced before. I find this to be very difficult while experiencing significant pain of any kind.
I was telling my H that my father abused me when his suffering was likely very acute and he was not receiving help. If he had rec'd help and wise counsel before having me, I would have had a chance to not have had the abuse. For myself, I can get help for my pain. I can seek to not live in a constant state of suffering, so that I can make space in myself for love and healing. Then, I can be able to feel and give love in greater quantity and quality. This is my goal. When my body is dead, my spirit will only judge how well I used the power I had here to do that for others, how well I navigated pain and still loved.
When my grandfather was dying of cancer, despite being in a lot of pain, and being in the hospital, unable to move from his bed, he was loving. I was 8. When I came into his room, he managed to smile, and gave me a hug. He asked me about my spelling tests I had been working on improving, and showed me that he cared. Now that I am older, and have been in much pain in hospital myself, I see how difficult it can be to separate the mind from pain/fear and think of others needs first. It's easier with kids, but it is a challenge. This is what we're working on. Don't give up. Your kids and grandkids love and need you. You are of the greatest importance to them and no matter what happened to you or what you did in the past, you are able to be and do what you want now. Tell your inner child that you are an adult who choses to love, and to love and heal the past, present, and future by your strength.
Much Love to you and your family, Muse
