<human>: Some background: we are juniors in highschool. I have a large social circle, but there is a smaller, tighter group of myself and 4 of my best friends. We always hang out together and we are like a brothers in a way. We are all there for each other, and we are all here for my friend in his time of need

Now some background on my friend : his parent split when he was young, so he was raised by his single mom. She was a very kind and loving person. 

On Saturday, one of my best friends lost his mother, and the only person he was living with. He has moved in with his brother who is in his mid 20s and lives a few towns over. He is still going to the same high school and all, but this is just so crazy, it doesn't even feel real.

I never even thought I would ever have to do any of this, but what are some things I can do for/with my best friend in the coming weeks and months.

Could you distill the essence of the text into 1-3 sentences?
