>>79554 (OP)What warranted you to go to a mental hospital? Solving it should be your top priority, unless it's something severe/out of your control.
Regarding your question, I think people like the ones you describe are very mentally unstable, and no, this doesn't mean you can automatically empathize with them. Their brains work differently from your own, and mental health problems make their logic nearly impossible to understand. Find someone who'd love you instead.
