Your Exo/Endo Hellscape
I'm not a scientist. My parents were, but it didn't take.
Anyway - there's this concept of exothermic and endothermic. Something endothermic absorbs heat and causes the surrounding temperatures to drop; something exothermic releases heat and causes the surrounding temperatures to rise. There's a fun physics joke of "Is Hell Exothermic or Endothermic?" (go Google it, I'll wait - aww heck, here's a link: https://www.albany.edu/faculty/miesing/teaching/assess/hell.html)
But back to your query: I would say first step is identifying your personal Hellscape here. Are you exothermic or endothermic? Do you give off love - i.e. loving folks caused your processes to radiate energy and thereby absorbed your excess heat and passion in a healthy fashion - or do you absorb it, effectively giving off a cool vibe whilst silently taking all that you can from folks to the point where without their love you feel you no longer have a source of heat? If one of these two processes sounds morally superior than the other that's not the case; both are valid methods of operating. An exothermic person may require the coolness of endothermic friends/family/partners to absorb their excess energy, just as an endothermic person may thrive on others and remain steadfast/loyal to them in the process.
The point to identifying your personal Hellscape is to best understand how to deal with it. If you've lost a main source of heat, then finding another seems the logical solution; maybe it's another person, or perhaps it's another group or space that provides that comfort. If you've lost the person who absorbed your own passion, then maybe finding alternate channels - again, possibly art/hobbies not just another person - could be your means of avoiding an unwarranted explosion. Either way it's important to identify what you need before moving on to find it. Otherwise folks might give advice and it won't take; only you know you.
And whether exothermic or endothermic, Hell is nothing if not personal.
