Sometimes when we have such a powerful drive to help (rescue?) others it is a sure sign that we need help for ourselves - and the only way we know how to get that is to give what we need so badly to others, sometimes others who don't actually need our help. We project our pain and struggles onto others and then try to rescue ourselves in them. It's something that we learn as little ones in powerfully co dependent families, the only way we can get our own needs met. I wonder what the pay off for you is in needing so badly to 'help' others? How do you see yourself being able to help here?
I may be way out but something doesn't feel right about your drive to help and I feel wary after reading it. Perhaps it might be worth exploring with a therapist what this drive in you is about, and getting your own help too - you will then be in a better place to really help others.
I have also read all your previous messages and am worried that you seem to want to isolate yourself with those who are vulnerable by encouraging them into private messaging with you - as if you are infallible and know it all - you aren't and you don't - that rings alarm bells to me, especially on behalf of the vulnerable people who you could hurt. Best leave support on the forums out in the open where it can be a collective kind of support.
