Hello GManInBlack, I'm sorry for what's happened and to know that you're struggling with anxiety is disappointing for you.
Sometimes our closest and dearest family or even friends are unable to continue talking with us, simply because they don't have the understanding of what to say or how to deal with us, and I've lost many close friends in the process.
I'm not sure whether or not you have actually met each other, but perhaps they haven't replied because they want to help you and are trying to find out the best way to do this.
Maybe you could meet halfway, that's something to offer so you can get their feeling.
Can I ask if you have been able to speak to anyone else about is concerning you now and in the past.
