Thanks for filling me in. For sure, if it can be avoided, and it doesn't seem like the possible benefits outweigh the detriment, we don't want to have you doing anything that could result in you being any MORE isolated or losing any of the agency you do have, like losing the loss of your phone.
Again, I hear that you want them to change. (Me too!)) But I just am not realistically seeing it. Your older siblings could probably tell you more about that. I really do think that ultimately, it's going to have to be for you to create your own autonomy here and not depend on them changing. I'm sorry that's the case, because by all means, I'm on your side here, and on the side of you having the kind of independence that I think is age-appropriate for you, something I don't think you have anywhere near.
I haven't heard about this friend before. I hear that you don't have money that would make moving into a place with this friend work right this minute, but this does sound like a maybe prospect to think more about: can you fill me in some more?
I asked again about possibly connecting you with disability services, and you didn't respond to that: is that something you might be willing to reconsider? (While I'm asking about disability services, do you know if your parents get any disability income from the state on your behalf?) With the guidance counselor, can you check and see if they're offering remote appointments? Since you are attending school online, chances are good that support services like that are also offered online.
One more option that I spaced out but that a visiting friend here mentioned when I was telling her about you and how frustrated I was in our desire to help you and our feeling like we kept having such a hard time finding ways to do that was support services and groups for adoptees. She reminded me that there are actually some good ones out there, whether you're a trans-national adoptee and you connect with those kinds of services or something more broad (here's a page with some of those, to give you an idea: https://www.americanadoptions.com/adopt ... ort-groups
). How do you feel about that as another help option?
