Via text my brother told me yesterday that my father took out a loan last year using the family business as collateral, spent the money, and can't afford the payments. My dad called my brother a couple of months ago and apologized to him because he was going to lose the business (my brother was going to inherit the majority of it). My dad told me that business was bad this season, but never mentioned the business was in jeopardy. He only mentioned his personal finances.

My father's whole identity is tied up in this business.

This substantially increases the risk of s/s. His whole life is crumbling. He needs help now.

My bad aunt owns shares in the business, but he has never told her about any problems. My brother told her about a week ago. She's visited him since, but he still didn't mention anything.
Since she understands my dad's identity rests on the business, and knows about his depression and personal financial problems, she'll believe me when I tell her about my dad's s/s ideation. She also loves my dad and has access to his wife. I think asking her to intervene is the best route to take.

I think if I went straight to my father's wife, she wouldn't believe me, and it would cause a **** show and add more stress for my father.

My father and his wife are on their way to FL right now. They're driving. They left yesterday.
I'm going to call my aunt later today. She can't call his wife while they're on the road. She'll have to wait until they get there.

I feel sick.
