Realizing I may have been less than forthcoming above (since I just used the same line elsewhere), here's a short list of some of the places I've gone to when I gotten dark. Most of these were during my first tailspin 15 years ago, some are frequent-flyers
Oblivion : Drug abuse, Alcohol abuse, Sexed up and ran with it, Partying
Violence : Fights, killing, hurting people, hurting myself, dangerous work, suicidal behavior (recklessness), outbursts, inappropriate reactions / not commensurate with the level of provocation
Relationships : Walked away from amazing ones, got into abusive ones, burned countless bridges / lost friends, refused to enter into any kind of relationship (romantic or platonic)
Basics : Unable to feed, dress, or otherwise take care of myself in any meaningful way
Misc. : Homelessness, Joblessness, Total isolation, serious isolating (2 different things)
Other Symptoms : Damn near constant anxiety attacks, flashbacks, nightmares, insomnia & sleeping round the clock, total loss of all of my emotions, no emotion but anger, trusting everyone/trusting no one (2 sides of the same coin), constantly on the alert unless I was numbing out / oblivion seeking in order to get a break from my own mind & senses.
Plus probably a bunch of others, feels like I'm forgetting stuff, but thinking about all of this has made my head very loud. No. I never sought help the first time around.
