One of the hardest things is piecing yourself back together again after breaking into a million pieces.
Trust.
You can trust someone with information, or trust them to get a job done. Trust someone to have your back, trust someone to be there, no matter what. Or trust someone to keep you safe.
The worst part in misplaced trust in a person is that when you give that trust to another being, that trust is completely contingent in your very own personal trust of the self. You are trusting yourself, your sense of judgement, in being able to believe that this other person is worthy of keeping your trust.
So, when they decide they no longer want that burden, when they decide that hurting another person to relieve their own stress in life is OK, because they have already done the calculations and decided you will be OK even if your trust in them was wrong all along, they forget that the implications lie on a much grander scale. Because, even after the damage is done, and they have moved on, that huge earthquake is only the start of an avalanche of aftershocks: you are left stranded in a place where you cannot even trust yourself.
When you have moved from a space of casual acquaintance, slowly and systematically ingraining everything inside of you with this person's aura, their function in your life slowly becoming part of the very equation of who you are, so much that you would bet your life in that trust, nevermind your own sense of identity and trust, it goes without saying that once that little piece of trust is removed like a Jenga piece down there below the other million pieces which comprise you, of course everything, absolutely everything, collapses.
But it is all inside of you. And not any other person ever could imagine what it is like beyond that outer shell. Inside, you are juggling the pieces that have not yet fallen, and yet you are trying to pick up, and catch, the other falling pieces which are sharp, fatal, piercing you with pain. Inside, you are slipping trying to escape falling completely and utterly to that bottomless pit where your sense of self can never be resuscitated, and yet you are slipping on the shards which make up the slopes you are trying to keep a grip on with the soles of your already-ripped and bleeding feet, and mutilated palms, slipping on the blood, bringing you to your knees, on which you continue to struggle up. Inside you are suffocating, as the atmosphere around you is a vacuum-sealed vessel of building pressure, toxic fumes of self-hatred, green gaseous canisters of laughter assaulting you with no remorse. Inside, you don't even know which part of you is really you, and inside, you don't even know who you are anymore, not really.
Can you ever really—really—trust another person to keep you safe?
