I have no idea what to do?

I don't really know what it's like to be in your position, but I sure have an idea what it's like to be in Tai's position. I guess all you really have to do is be there for your son and be there with him through it all. Support him with whatever makes him happy and always be there for him. Let him know he can talk to you about anything. Ask him if he's comfortable to talk to his counselor about things. Things do get better. I hope everything works out greatly for you and your son!
