My 38 brother is under a lot of stress. He's had a tumultuous time the last 4 years, but all of it is due to his own decisions. His business failed, he spent time in prison, and fathered a child. It's important to mention he's always been an asshole towards people, and for this reason, I don't feel very sorry for him. I'm posting because I'm worried about my parents. My brother also lives with them. When he started his business 5 or so years ago, he moved back home to help save money.

When his business started failing, he started gambling in an effort to make money. When that didn't work, he started stealing (stole from his own family even), and that lead to prison. He feels his actions weren't that bad because he "panicked" since he was going to be a dad. Ever since he's been living at home again, he claims he sees drones following him. He thinks he's being gang stalked. My parents tolerate his behavior because he's their son. Yeah he's my brother but he's also an asshole, a narcissist, a pathological liar, and a thief. To me, these traits are a choice. I've called him out about the fact he thinks drones follow him and he absolutely flew off the handle. He has the same reaction when people tell him he's wrong about something. Just today, he tried showing me something on a website that he thought was "weird", and I correctly pointed out that it was just something broken or needed updating, but he flipped out again because I wouldn't go along with his conspiracy theory.

I believe him to be just an asshole who wants to blame his failures on anything but himself. Or maybe he's suffering from a mental illness? If so, how does one get help for someone who would never admit they need help?
