unfortunately, a strong fact of life is that everyone is inherently selfish, even just a little bit. i don't mean in a bad way - we all are focused on our own lives. they might not mean to or aren't a very selfish person, but the reason they do not pry is that they aren't thinking about it. if you need support it might be worth even calling a close family/friend and saying ''hey. I'm not okay. Can we talk?'' 9 times out of 10 they will be there for you. When people ask 'how are you?' in our society it is mostly a polite thing to do, not that they do not care, but because they are focussed on other things.
i am sorry that you live far from support - is there a psychologist you could see close to you? that really helped my GAD.
things WILL get better. you need to surround yourself with support, professional or social.
