Adoptee how would you feel if you found out your birth mom was trying to contact you?

I would be estatic if my birth mother contacted me. I have never seen her, I was 3 months when I was taken from her by the County Welfare Dept in 1951 and she disappeared after that. My adopted mom has always been very supportive of my search to find my mother, and she has "adopted" all my other siblings, half siblings, cousins, nieces and nephews that I have found over the years - including my nephew who is in Arizona Prison - she writes to him weekly. I consider myself very fortunate to have her, but I do have a longing to find my birth mother and I've been searching for her since I was 16 (1966).
