Apologies if this isn't the right place to put this, but thought it was probably the most relevant topic! Am a regular, but have namechanged as I know some people irl know my username.
As a child my brother and I grew up more or less alongside my cousins, who were the adopted children of my uncle and aunt. We were all quite close, but I was particularly close to their daughter who is more like a sister to me than a cousin (hence putting sister in inverted commas in my OP)
I've known for a while that my sister has been searching for her birth mum and siblings and have been supportive and encouraging I hope. I found out today that she has found her birth family, has spoken to them and is obviously over the moon about it all. Her birth parents seem pretty cool about it and happy for her, as am I.
So I was totally shocked to discover that part of me is really sad and worried about how this will affect us all as a 'family'. I know it sounds really selfish and unfeeling, but I'm scared that she will prefer her birth family to us and won't want to know us anymore. It sounds so daft writing this down, but I've been feeling so upset about it ever since I found out and wondered if anyone who has been through a similar thing can reassure me/kick me up the arse. I love her and I want her to be happy, but I don't want to lose her.
