My best advice is to engage in an activity together, aka playing games (no other things you can do rlly), sometimes it is more about keeping them distracted then about reasoning and comforting, sometimes just spending time with them can help distract them from thoughts, this is of course on the assumption that you are already comforting/speaking to them. Among us is fire recently and it is a good choice. Personally my issue with a friend is that I do not get replies from them when I am asking for their wellbeing so to me spending mutual time together is important because you actually get to communicate and you can catch red flags from their speech especially if they weren't planning to say in the first place! Otherwise if it's a chore to you(no hate because not everyone is born with the capability to love more than themselves), I suggest breaking the friendship as half-heartedness is arguably worse. Cheers mate! Hope you're doing well too, when youre with them remember it is always about them, but dont forget to love yourself as well in case you get lost trying too hard to help, all the best
