I know exactly that feeling you describe--when you realize that whatever you've told someone, it was too much, and they don't want to hear anymore. I always want to scream, "It's too much for you to hear? Try living with it!"

On the forum, though, I think people often read and do not reply for lots of reasons. They don't feel they can be constructive; they don't know what to say; they're shy, etc. I know that I tend to read and not reply in some forums, like this one. Although I do have PTSD, it's not combat-related, so I don't want to butt in.

If there are lots of reads without as many replies, perhaps it will help to know that people are reading and resonating with your words, albeit silently.
