When I moved last year (October), I had literally just stepped into the door at the end of a cross-country (South Carolina to Seattle) drive to a phone call from my parents. The day I had left, my brother began acting very strangely. Manic. Then violent. Had admitted to mixing drugs for a 'high.' They were calling to let me know he was under psychiatric care and was, supposedly, blaming me for it. (He was blaming me, not them)
This past Spring, he mixed various drugs again, went manic, and was arrested following harassing neighbors in his underwear. He was compliant with the cops, neighbors didn't want to press charges, so he just went into psych again.
Today, he's sending me the strange messages on FB that have preceded previous situations. I checked with my parents and they said he was manic this morning, but 'seemed normal' since. I've had to block him because the messages are either entirely nonsensical, or things like:
"I want to be me, but you took that, refused to let me be and made sure I would never amount to anything."
He is 26.
I have not been 'a part' of his life other than distantly in over a decade. This because of a few times in my teens in which he was violent towards me, made threats to kill me, etc. I have tried. I have really, really tried, because I'm jealous of those who are close to their siblings. I had thought that maybe once he was an adult... but no. I can't do this any more.
