You said, "I know that I am not to blame due to my birth and that they have to deal with their own baggage but I am hurt very deeply."
Knowing it in your head is good. It's going to be much harder to "hear" it in your heart, isn't it? It hurts to have your own parent connect your birth with the general problems of your family. Ouch.
My third child was unplanned, unexpected, etc. We had two teens (my stepkids) who were driving us crazy because they wanted to live with their mother, an 8 year old who would today be called "ADD-HD-LD", etc., and a 2 year old toddling, when baby number three came along. She was the easiest baby I ever saw. When she was a youngster, she was often quiet and moody, but she was so clever and funny when she wanted to be. She made me laugh more than all the others put together.
When she was old enough to hear such things, she did know that her arrival was unplanned, but we never told her she was an accident, a mistake or a problem. We told her she was a surprise that we didn't know we wanted until we got it. Those are the best kind. We have always told her that and I think she knows she's loved as much as the others.
My first baby was unplanned, too.....he started the whole marriage off by being born 7 mos. after the official ceremony, tee hee. We never blamed him for marital problems though. How ridiculous. WE were responsible for our lives and how we have lived them, not him. What a rotten trip to lay on someone.
