...cried through a meeting and, if so, what were the reasons?
I cried through a lot of meetings at my second congregation while I was still in good standing. I couldn't stop myself; I'd just cry quietly. In retrospect, I realize I was feeling a lot of pain at the lack of love in the congregation.
When I was DF, the first meeting I went to afterwards, I had a full blown panic attack, started hyperventilating, shaking and crying, and had to leave the Hall. I actually collapsed in the snow and cried. No one came to see what was wrong, although everyone in the last 7 or 8 rows saw me.
I pulled myself together and walked home. It was about 2 miles. Not too bad, but.....I remember a bad snow storm I walked to and from the Hall and everyone just rode by. Except one car with persons in it I had never seen before. A woman called out, "Sister, would you like a ride?" Being the good DF person I was (what an oxymoron), I said, "No, I'm DF, I can't". She then said, "But it is snowing and you are shivering". I said, " I wouldn't want you to get in trouble".
That was the only display of love that I ever received from that congregation, and apparently they weren't even in that congregation.
I felt so much love for that woman.
But yes, I myself have cried and had major anxiety attacks at the KH.
