Artificial insemination, Wales

hello. i am someone who was born by AID because my mother wanted to have a baby with her partner who was a woman. I have a really small family (no siblings) and sometimes i really want to know if i have any half-siblings, which is usually the case. There's no point wondering about my father since it would actually be illegal to find out who he is. Sometimes it makes me feel really alone and isolated because i don't know anyone else in my situation or anyone who can relate. It's really hard to admit this because usually i pretend that it doesn't matter and that i don't need to know the other half of my family. I just want to know if there's anyone else out there like me.
