Can you separate "who you are" from that worry? Seems to me it's a part of you and you wouldn't be you without it, for better and worse.
One worries because it was a helpful strategy compared to not worrying, but some (like me very specifically) can get attached to that worry to the detriment of picking up other mechanisms.
What I’m mostly talking about is that transformation happens through life’s journeys! Requires much less commitment to the idea, as it’s pretty universally understood.
That episode really got to me. Every time the screen goes dark and transitions to Morty realizing he's still trapped in the hole, something inside me freaks out too. It's like the show is forcing me to realize I'm not actually confronting these truths in my own life. I'm probably still in the hole, aren't I?
