Bang on. I’m feeling down right now (relationship that ended I’ve never recovered from years later) and no amount of chatting with people online is going to fill that gaping hole or help me patch it.
Professional help should always be approached first and foremost.
Of course, that’s not accessible for many people which is a shame and for that I have no answer, just that seeking to fill that hole with like-feeling people online is a recipe in disaster. Negativity breeds negativity.
