Sure, honey.
What I mean is sometimes you sound desperate to reach your "core" as though you're going to find a special kind of "thunk" with a prospecting tool while you're digging for treasure, and all of a sudden you'll break through and there it is. Almost physical...
I mean that I really truly believe that it's the way you talk to yourself, about yourself, that results in you not trusting that you have a fine, lively, vital, intelligent, full-of-promise and capable-of-happiness (okay, start with contentment, that's less triggery) self. You already have this capability.
It's a capability, not a static state. Your personality is in flux and that's okay. Your self-talk, and the language you use to form your thoughts about your pain and your hopes, are all what your core IS. You are MAKING your core as you speak to yourself.
So make it gently and thoughtfully and with as much care as you'd design self-esteem for Henrietta. One look at that old face and you KNOW she deserves to breathe and be loved, right?
Look in the mirror. Talk to her.
I like your IC work. Sometimes I've heard that literally finding an little-girl picture of yourself, posting it right by your bathroom mirror, and another by your bed in a sweet frame...helps. You can generate kinder more loving self-talk, imo, when you talk to her with compassion. Not victimhood, just love and compassion. Then in a while, try on some gentle humor.
At some point, the way you talk to yourself will open up, expand. You'll feel that your "core" is thoughts and feelings, and it grows more strong and happy as it expands. There's no hard kernel you have to protect. There are just new thoughts you need to make habitual. And I know you can. Are!
I'm sneaking this at work so it's not too well written, please tell me if you need me to be more articulate.
hugs to you,
Hops
