Thanks for your ideas and likes, guys. I feel the support and it means a lot.
My anxiety/emotional-mental storms are more like PTSD reactions, stemming from, well, (very early starting) trauma. I've already got different therapeutic modalities (psychological, chemical) going on now for almost a couple of decades. I can go through long stretches feeling fairly stable, with light anxious undercurrents, and occasionally extremely hard-to-manage reactions like this week. The thing is it's hard, when you're in it, to not freak out and think you're going to stay that way, because it's so intense and can be unrelenting. When it happens, I always regret not having already established meditation techniques.
Obi, I once had irritable bowel syndrome and a couple of sessions of hypnotherapy got rid of 90% of it, and I no longer have it. I later tried it (a few sessions) for anxiety/mental meltdown and it didn't do anything, although it might have eventually done some good. I am interesting into looking into self-hypnosis videos, though.
Bucky, unfortunately I've just developed foot pain that means I have to stop running for a while - just when I needed it! So that's partly why I'm trying to find other means.
When I get this way, I need to feel safe/secure and stop my mind from its hyper-alarm survival trying-to-find-solutions-to-any-and-all-felt-present-and-future-catastrophes mode. The way I've been made to understand it is a visceral fear reaction rooted in past events/contexts, triggered by whatever subtle or not-so-subtle current stressors, that takes a hold of the mind, which projects those feelings onto the future and tries to "solve" them. The thing is even when you understand this cognitively, while it helps framing it, it doesn't necessarily neutralize the reaction if it's intense enough. I've been going from videos that guide towards feelings of calm and security, to some that try and create a meditative distance from the overactive mind and obsessive rumination states, like this one that I listened to last night:
It did help to some degree and I'll be getting back to it.
Meanwhile this helps too when I just want something in the background that's calming and comforting. :)
