<human>: Last night my bf and I were getting ready for bed and his older brother called. We'll call him Adam. 

Adam was ranting about Panic attacks and how much better he is than my bf. He mentioned having overdosed on meth(?!) Over the holidays. He was all over the place and sounded really fucked up.

My bf asked a bunch of questions and told Adam he needed to get help. Adam became really abusive and was trying to be intentionally hurtful. He hung up on my bf. My bf was (i think) pretty reasonably upset.  He texted Adam and told him not to try to talk to him until he Comes back into the state.

Adam replied with even more mean stuff, about my bfs job, his hobbies and even started talking shit on me. I don't care, he's only met me twice, but my bf got very upset. I've never seen him that close to tears before.

How do i support/help him through this?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Boyfriend's brother called to brag about his heavy drug use, his od and was really mean to my bf. What can i do or say to help my bf?
