Excellent question, elnarco!

For me, breakdowns involved severe depression, unbearable anxiety, a very noisy mind (music, loud noises, repetitive words, talking), agonizing insomnia, delusional thinking, constant extreme fear of terrible things happening, feeling that loved ones don't care about me and barely tolerate me/are angry at me, sensing my beloved pets who have died around me, sensing the presence of people who (I don't think, at least not on this earth) are really in the room as being near me, suicidal ideation, a manicky kind of creativity, nausea and stomach issues, headache...that's about all I can think of right now, but you get the general idea.

I would like to read replies from more people on this thread.
