It’s sad, I think, to realize this - again - as an adult, that you can never be sure who to trust. Because you can never be sure who will betray you or play you or just not care. People who are supposed to be a good friends. For all they know, you could be alone in your room with a knife to your wrist again. You’re not. But they don’t care regardless. Your need for advice doesn’t concern them, nor your loss of sanity.
I guess you’re never too old to find out who your real friends are.
