Though I likely had mild euphoric periods before, my first major symptoms started at 14/15 years old with anxiety and depression followed by a severe mixed episode that again became more purely euphoric hypo/manic by 16 years old.
A brief list of the events/ramifications included:
14/15 - Anxiety and depression (prescribed Buspar/buspirone), stopped ballet and skipped school days almost failing grade.
16 - Severe mixed episode, passed out at school coming to in hysterics, sent to child therapist, changed schools because of it.
16/17 - Wanted to find God so went to numerous churches in town, soon after joining the Catholic church and developing religious fervor.
17/18 - Stabilized. Religious fervor eased.
