I really relate to what you said about slow motion explosions around you, because when I'm alone time seems like it almost does move in slow motion. I also don't understand the world anymore, and get into a stage of disbelief because it seems like people don't care about the same things that I do. I just don't understand how they keep going.Distracting yourself is part of it.
But it hides the true fix... and that's understanding what IS and isn't your problem.
Research personal boundaries and codependency. It's changed my life. I still struggle and I wonder if I always will... but everything you mentioned always felt like slow motion explosions around me closing in and suffocating me. And now.... it's nothing. It's so much calmer now and only really gets to me when I'm totally exhausted and drained.
So yeah. Having been where you've been and gotten out of it... that's my advice.
Then take up any hobbies that exercise solely your Ni/Se. I've noticed that works best. Fe can get us in trouble sometimes and the reason I think solo hobbies do so well is because..... it's just us. 100%.
So you're saying that you found peace through looking up those two subjects? What did you do with that information? I read about both, and can't be exactly certain of what you mean. I guess I'm just looking for some more elaboration.
