You are not alone; my mother tied my sister and I up threw us on a patio mostly outside, naked. Two hours later she came on the patio with a knife and I saw murder in her eyes- when she got close I kicked her hands and the knife flew. My hands were tied.
She woke from the state she was in and started to cry. Later we found that the thyroid medicine she was taking was making her hallucinate. Still didn't explain all the crazy.
I left home at 16 never looked back.
Life is not a box of chocolates it is a never-ending struggle - with only moments of complete bliss. Surround yourself with only people who have dealt with their shit from the past. Then live the life you have.
I wanted to share because you did.
