This is the first time I've responded to somebody else's thread.

I can relate to your son's struggles in quite a few ways. I've always been a loner and prefer to play by myself rather than with others. I remember one day in junior school—about six or seven years ago—when a group of students crowded round me, and I got really frightened and upset. I also struggle with depression and thoughts of worthlessness and self-hatred.

Your son may be insecure, afraid to show people he doesn't know about his struggles, so he bottles it all up inside him and hides his anxieties from the rest of the world. I do not blame him for this, in fact I've done this myself. I was once heavily affected by an incident in my life that most people would be able to get over quickly, and kept it to myself for over a year before finally opening up to my mother and asking for help.

Anti-depressants don't work for everybody, as Hellion said. It can take doctors a long time to find the correct anti-depressant that works. I am sorry to hear that your son was so upset over the anti-depressants not working. I agree with Hellion and nowheretohide when they say that he may have asperger's syndrome, but may also have other struggles. PsychCentral has a page that lists the symptoms of asperger's syndrome, but I'm afraid I can't link you to it because my post count isn't high enough. Sorry about that.

As for talking with his psychiatrist about his struggles, that's a tough one because they don't believe you. I'm very sorry to hear that. Have you told him/her that he conceals his hidden anxiety and anger? If so, then nowheretohide may be right that this psychiatrist may not have a good understanding of asperger's syndrome, in which case it would be a good idea to find somebody who is professionally trained in the spectrum disorder.

Now, this post may not be very helpful; all I've really done is talk about my own experiences and back up what Hellion and nowheretohide has already said. With that being said, I still hope your son gets the help that he needs, and you find peace of mind.
