Backstory to this: I was adopted and until I was in college, didn’t know I also had biological siblings. My older brother was engaged to someone I was at school with, who helped him find and ultimately introduce himself to me. We were still just teenagers, so I think we weren’t ready anyway, but long story short, we seemed to get on well at first, then it seemed like he started being hostile on the phone to me, though sometimes he could still be ok. I didn’t try to push it too hard, in any case.
In the end I stopped trying to call or text, as I was afraid I’d either never get a response or he was just going to blow up at me. The last couple of times, I think I got other family members but didn’t tell them who I was. Looking back, one of them likely knew, however. I realise now I probably should have sent a final message, but I honestly didn’t know how to handle it any more so just dropped contact. Maybe it has come back to bite me…

I’m now trying to get in contact with my siblings via a social worker, though haven’t had a reply yet. It’s been about a month; she did say it can take weeks to get a response but I’m not feeling hopeful right now.
We can only find this brother’s address (very close to where I currently live… but it’s not like I can just casually drop in ), so she has had to write to him and hope someone responds.
All this just really hurts right now; not knowing what will happen, and bracing myself for the pain of potentially getting no reply at all.
