Hi M.
I am so sorry for your situation. It is so hard to help those in that way. I know a little and have a few suggestions. And please know that I am not attacking you or your son, just suggestions. First, if you are able, maybe you could start a therapy session also. This will help you deal with your emotions and concerns for your son. Even if it is with the same counselor, and find out if your son likes his counsleor. Before any improvements can be made, you son has to gain trust in his counselor. This can take a lot of time. He has to feel that he can open up to them. It typically takes me a few months to a year to learn to trust a new friend, so imagine how hard it is for a 13 year old to trust not only an adult, but someone he is forced to see.
Second, take a good look at his friends, habits, and living environment. There is something he feels guilty of, ashamed of, doesn't understand, trust, or some issue along that path. There are many issues at hand I am sure and not just one. Perhaps he feels inferrior and this is his way of attention or is ashamed of something he has done or does not measure up to and this is his punishment. There are many possibilities. Be open about it and allow him to express his emotions and feelings. Most importantly, give as much love as you can. Remember that discipline is still love and respect is love. And my last suggestion is to hang in there!! Make sure you are able to trust the counselor. There is nothing wrong with getting a new one if you are not satisfied with this one. Not every counsleor is great just like doctors.
I wish I could help more!! If you need to vent, please email me and I will listen. Sometimes that helps me when I am angry, scared, and all those emotions rolled up into a ball. Good luck!!
M.
