My Family Reunion

The reunion has been almost a year and the time has went very fast. I'm past 65 years but had a place missing in my heart for my birth parents. And than, my birth mother found me. This has led to an incredible journey. My birth mother and I have had many phone conversations prior to meeting 2 months later in person. I met my sister,birth mother side, at the same time. I have 2 more brothers who I have not met personally. My sister lives within 1 hour of me, but we have not continue with a relationship. My mother lives on the West coast and we continue to visit by phone and are planning another visit this coming year. She gave me information regarding my birth father. Next step was to find my birth father and my siblings. I discovered my birth father was deceased. I found my sister, birth father, on facebook and she introduced me to my other sister and 2 brothers. This sister,father's side, has remained close to me and we talk and have met once. One brother and I have chatted on occassion but have not developed a relationship. The other brother and sister have not accepted me as their 1/2/ sister. Where do I go from here. Do I accept what is and give up? I feel sad because they are so much a part of me and yet they do not feel the same. In some ways I'm still rejected because of my difference. I'm adopted, but I'm illegitimate. The sisters and brothers are embarassed becasue of the affair. Is my mother ashamed after all she is 86? I know she is wondering what will her friends and family will think. In my adopted family, I'm legal but not of blood. I grew up with an adopted brother and we have grown apart after our adopted parents died. In school family trees were the homework of terror and nightmares. Than I watch my children and grandchildren go through the same nightmare. Cousins I grew up with and played with do not understand why I care about the family past(their history). I even had one cuz say but you are not blood, why does it mean anything to you.
