((((Kid)))) I think Mallard is right, you are probably in shock. To have these kinds of facts just dumped on you with no compassion along with feeling such a sense of not mattering to your parents because they do not remember the most basic of facts, would have anyone reeling. Please be very gentle with yourself. I do not know if you have outside contact with your therapist, but if you do, this would be a good time to reach out. I am very glad that you are here talking about it, and hope you can continue to use the forum as a safe place to reach out and be able to express all of your (no doubt complicated) feelings.
