In my limited experience, when a person is feeling overwhelmed by events in their lives, when their emotions are running out of control - that is the most difficult time to make logical, rational decisions.
Do they pick up a phone and dial the local mental health help line? Probably not. That would be the logical thing to do.
If, however, a person had been closely affiliated with a discussion board and had formed close attachments to the participants, they might reach out for help there. That would be the emotional thing to do.
None of us, whatever degree of qualification we might carry, can counsel a person with mental health problems. This is simply not the right environment to give serious help.
We can, on the other hand, be supportive, non-judgemental, kind, and encouraging. We can also restrain ourselves from words which could cause further injury to a vulnerable and suffering individual.
I don't read much here, but doing a quick search on SP's posts, it's fairly obvious she feels (and whether her feelings are valid or not is something I can't say) she has been "marked" by the board administration. It is very easy to say: "Hey, it doesn't matter what some people think of you...get over it."
Not the best of advice in this situation, IMO.
