Hello MusicDad
I’m so sorry to hear what you are going through, it must be devastating for you.
My uBPD son has lived his life out of his backpack off and on for quite a few years, and all his stuff is left here in his bedroom that he will never sleep in ever again. So I understand what you are going through and my heart goes out to you.
You recognise that he is an adult now who is responsible for himself and his own life choices. You are very wise to acknowledge and accept this. One of the hardest things that a parent could have to do is to standby, and watch their child, who they know needs help, knowing that there is nothing that they can do. How painful that is.
You say that you feel that there is nothing you can do for him, I would like to join
Huat in telling you that there is lots you can do for him. And for you too. If you look to the right

there are lots of tools and different resources that will help you immensely. What do you think?
You have already taken the first step by posting here and as
Huat says, you have already reached out to another member too. Both positive moves.
We are all here to help and support you as you move forward.
