We initially looked at finding a donor in Aus having not done much research on overseas. We did everything advised and found the whole process very uncomfortable. Felt like you were constantly competing. We did not want a donor becoming part of our lives and becoming friends. I also have a mental illness, which is very controlled and my psychiatrist has supported me. The counsellor at fertility clinic told us we need to tell potential donors of this and I understand a donor choosing someone else over me if concerned about mental illness.
So I started research on overseas and liked the idea of an anonymous donor. I come from a divorced and remarried family and to me my step Dad is my dad. He was the one always there for me. My biological father is just that. I did not have a strong relationship with him. So for me the genetic side of things was not as important as the life and love you give the child. I also spoke to someone who was adopted and she also felt the same.
We are in the tell the child starting young camp. I would always fear that something may go wrong health wise and need a genetic match only to find out at an already stressful time, there is no match.
All a personal choice and we make the decisions also based on our own life experiences. Good luck with your decision.
