I am losing it a bit and don't know what to do.

I found out the oldest son of some friends had been abusing a boy/boys – and charges have been filed. He is 15 (I believe) and has been through so much himself (adopted at about 5 after experiencing years of abuse himself). I guess this also isn't the first time it has happened – I think the other time it was his brothers. I didn't know about that until yesterday.

I am so anxious and triggered.
