Trying to relax

Can’t sleep. Woken up By the dog sitting on my pillow, panting from lightning and thunder. Stayed awake due to difficult thoughts and feelings.
I am a mother and I want my kids to be safe and healthy.
My son was just inpatient for near a week because he was having suicidal thoughts And feelings. he had recently moved out. I’m not sure he was ready to move out, and would he be better back here?

I am so worried about him and it’s hard that he is not here. He sounded really down last night, after he had been sounding better the days before.
He said he got triggered by someone staying at his place (ex gf who is crashing there for the weekend). I tried talking to him about it, but he wanted to hang up the phone. I told my husband I was worried and my husband contacted my sons roommate, he told the roommate that the ex gf should go stay somewhere else by our son can’t handle having her there.

In the end, my son texted me that he is ok. I don’t know what all my husband said to the roommate and what all the roommate said to my son, but on one hand I’m upset if I overreacted and caused drama and interfered . On the other hand, I felt very worried and annoyed that this gf is crashing there after dumping him, when she can go stay somewhere else.

I know my son is an adult now, just barely an adult, but he was inpatient and he said part of the reason he had been so affected was due to things happening at his new place, and that his gf broke up with him and was still crashing at his place on the couch.

Hes wanted to stick things out in his apartment (he’s been saying that since he moved in there because he said it’s hard and he misses being home where things are familiar). He said he wants to move on from the gf. How can he move on with her in his face? He said she could stay to be nice.

This is such a hard time. I’ve barely slept due to adrenaline from worrying earlier. I have to leave for work in an hour.

I’m just not sure what happened last night? This is hard to navigate.
