I agree that they probably do want to help, or would want to if they knew how bad things were for me. But, I also have a major self-worth issue where I always seem to put myself at the bottom of everyone's list, regardless of whether or not they even know that I want to be on it. A constant struggle for me, really.
Trust is, of course, another difficult one for me. I fear others' reactions, ridicule, rejection, ulterior motives, gossip, conspiring against me, etc.
More learned behavior and observations: if you need to ask for help, you aren't taking responsibility for yourself, not being "manly" or are considered a weak person.
A better topic subject might have been "can't reach out to anyone" rather than the one I chose, because I do have people to reach out to, it is just very hard for me.
