I get anxiety about posting because I try to be helpful but often misinterpret what’s being said, and I’m guilty of having knee jerk reactions to certain things. I haven’t had too many “smackdowns” (especially here) but I think I have a fear of making mistakes or offending people, so I often end up being ‘milquetoast’, when I should be truthful even though I know it may ruffle feathers (in the interest of helping, not being offensive for its own sake).
If I feel people might be upset I generally hold back, though.
If I get upset by replies (not here but other places I have), I tend to totally withdraw for hours and not know how to deal with the feelings besides block them out.
