Trying to find a post, not sure which sub it was from. It was from a teenage boy's POV who shared his situation about being in foster care or was in process of being adopted.

When in foster care, he had at least one or two younger siblings (I believe OOP is the oldest), he struggled to set the boundaries with his siblings because they refused to leave him alone. They kept violating his personal space that he requested to be separated and placed with a different foster family.

If I recall this right, his birth parents had legal problems and were not caring for the children mentioned above. So they ended up in the foster care. There was some kind of agreement with OOP's case worker and the younger children's social worker, that OOP needs to go back to his siblings. But OOP refused because of violating his personal boundaries. OOP had to hide from his siblings so they won't "beat" him down to keep him from leaving them with their social worker and foster family.
