I was also adopted and while I know I couldn’t stay with my birth family, I still consider them to be a part of me, in some ways more so than my adoptive one.
I met my brother (who I wasn’t told about) as a teenager, and now I’ve just started the process of reconciliation with him and my other siblings; I’ve been through a lot of disenfranchised grief and anger over the years, especially lately, as I found out both my adoptive and bio dad were addicts (addicts aren’t supposed to be allowed to adopt, but my adoptive dad’s alcoholism was covered up. I don’t drink, but I hate the fact it’s the main thing my life has revolved around, including being moved into pubs my dad was “working” in, to him having countless falls at home and out… plus there’s so much more I could literally, and comfortably fill a novel. Adoption is apparently meant to provide the chance of a better life for a child, but in my case I don’t think it was a huge step up).
