Ok so for context, me and my brother are twins and he has terrible anxiety and panic attacks like me but his started recently whereas mine started about a year or two ago. He’s become a hypochondriac and is racking up medical bills over nothing by thinking he’s dying randomly. When he panics, he forces himself to throw up almost everytime which doesn’t help anything and if anything makes his hypochondriac-ness worse because now he thinks he’s sick.
He’s been to the ER once out of random and realize “oh shit I don’t have health insurance” and is awaiting the big bill and went to urgent care twice eating away more money.

He said he needs help but has made no effort to actually seek help and is a raging narcissist whenever he isn’t panicky. When he panics (almost nightly kind you) he’s almost like an infant and anything harsh is bad and is very pouty. 

The only reason I may sound annoyed or angry in this post is, I’ve gone through the same thing but got help before I went crazy, which I strongly believe he is. 

What do I do? Does anyone know what’s wrong with him?
