Don’t know what to say or do

I have a situation with my family that has me in a state of not knowing what to say or what to do next…

In a nutshell, here are a lof of the C’s of the situation:

I have a 25 year old godson (he’s also my cousin)
He’s been troubled for years, struggles with addiction (alcohol and drugs)
He’s been in and out of rehab for the last 5 years
Has recently been put on disability by his psychiatrist
Has been diagnosed with severe anxiety and depression
Tried to commit suicide at least once, has been hospitalized a few times due to suicidal thoughts, at least once was hospitalized against his will (just a few months ago because he was a potential danger to himself)
His dad (my uncle) died of cancer 2 weeks ago
My godson had to try to revive his dad but it was already too late
3 days ago, I took my godson out for dinner and movie to spend quality time with him and hopefully give him a change of pace from what he had to deal with
That same night, he decided to drink, steel his friend’s car, drive and got into a car accident (fortunately not hurt and did not hurt anyone other than the car is totalled)
He’s being charged with multiple offences as a result of that night, he may go to jail

So those are the C’s. I know they are neutral. I have done some work around my thinking about this. My natural reaction is to try and help and solve and make it all better. I know that’s not for me to do.

But part of me feels like I’m a coach and I should be able to help him. Part of me thinks if I were Brooke and had her skills, I would be able to help him. I need to coach myself through that.

Mostly, I just don’t know what to say to him. I don’t know what to do next. I feel stuck.
