Angel, my S14 has been seeing a C for OCD/anxiety issues. In our case, his M and I went to his first appt with him so that the C could understand what we thought the issues were along with S. Most other appts he went alone, but on occasion his M or I would have our own sessions with C.
Even though it is your D12s issues, it will be important for you (and H if he can) to meet with the C. Sometimes an outside observer is a better judge of our behaviours than we are ourselves.
It's so much harder on our kids than we realize. They're little troopers on the outside, but it tears them up inside.
I'm happy you and D are getting help, keep up the great work!
