First time posting in a while, looking for advice.

My Q was my ex boyfriend, and I’ve done a lot of work to heal from that relationship.

I’m posting today because a college friend’s mom asked me to drop in on her son today. He and I live in the same city and we had plans last Sunday that he suddenly bailed on last minute. I didn’t think much of it until his mom (who lives on the other side of the country) called me desperately this morning and shared with me that he has been binge drinking himself to sleep and is now not answering her calls. I did not know my friend was going through this (bc we had lost touch for a while, until I moved to this city a couple of months ago). I told her I’d be happy to help and check in on him, but after hanging up with her I started feeling a lot of anxiety bc it has triggered a lot of feelings from my previous relationship. My Q used to binge drink himself to sleep and when he admitted to me he was an alcoholic, it was on the phone during a period of long distance that was due to the pandemic.

I know this situation with my friend is obviously not about me and I want to lend support, but I’ve been here before and I don’t want to make the same mistakes. Does anyone have any advice for how to move forward? I will of course be dropping in to make sure he’s ok and try to bring peace of mind to his mom, but I don’t want him to feel cornered by me and I was already in a situation where someone took out their anger on me and I’m scared of it happening again.
