Where do I begin?

I just finished reading a book called "That Went Well" by Terrell Harris Dougan. The author tells the story of growing up with her mentally disabled sister. The story continues into adulthood where the author is left to care for her sister after her parents have passed on. Some of her stories made me laugh out loud but many of them made my heart ache. I know the stories all too well. The stories are similar to many of my stories of my son,Colin. So many times I was taken back to a time when Colin freaked out in school because the noise bothered his ears or when his routine was disrupted and the only way he knew how to handle it was to have a full blown temper tantrum (sometimes in public). Oh yes,I know those stories all too well. I loved that book because I could totally relate and I felt like there is someone out there who knows exactly how I feel. It also made me think of Blake,my "general ed" "typically developing" "normal" son. You see,he is the one who will have the burden of caring for his brother when my husband and I are gone. One reason I did not have a 3rd child is because I didn't think I could handle another kid when I have a son with special needs. OR "what if" I had another special needs child. Two would be too much to handle. After reading this book I now wish I would have had that 3rd child so Blake would not be the only one responsible for his brother later in his adult life. I do know this....I was given my Colin for a reason. He has something to do with my purpose in life. I want to help other families who might be struggling with a special needs child. How? that I do not know. Sometimes I think it's just nice to know you are not alone.
