Someone likes me, or even says something nice to me.
I get (too) happy, or excited.
I respond in kind, but take it too far, too quick.
They get alienated.
I get depressed.
2 days later, I don’t remember, or don’t care enough,
or just get excited again,
and can’t take the worry and mental mind f… of
“should I say that, should I not, don’t say that, it’s fine, no it isn’t, er, think of sth else,”
so worry about that too, lose the impetus, get drained,
so I either say it anyway, or (bitterly) regret not saying it, and/or get frustrated by either outcome
(not saying it, or getting a bad response from the other party), so I can’t bleeding well win, can I ?? ..
Repeat the process.
