<human>: Can you provide a brief rundown of the text in within 3 sentences?

I'm incredibly worried about my younger cousins; I have been for some time, but tonight it's different. Today their father killed himself. Their parents have been separated for some time, and my cousins have been living with their mom and grandma out in the country for a while. I'm not even sure if they know yet. 

I suppose what scares me most is the oldest of my two cousins has fairly serious mental health issues. He was diagnosed with depression and ADHD, and has been taking all kinds of medications to treat these diseases for 3/12 years of his life. 

The younger of the pair also frightens me. She is intensely emotional, and struggles with expressing them. 
It's a long story I suppose.

If anyone has some good advice or experience, I'd love to hear it. I'm wondering if there's even anything I can do.
<bot>: My uncle killed himself today, leaving behind his ex-wife and two  children who struggle with depression and coping with their parents divorce. I need help.
