My son is finding college really challenging and is becoming isolated.

Hi, my name is Debbie and I am really writing this on behalf of my son. He is 16 and this is his first year out of school. We thought college might be a less stressful environment than school because he could concentrate on the subject that he enjoys (art) and not struggle along with things that didn't interest him at all. The trouble is the art course he was going to do proved too much for him (both too noisy and too fast) so he was given the chance to try a different course with more support. This also proved too much. His anxiety is extremely high and he is prone to meltdowns. Because the college is a whole new environment with new people we thought he may need time to adjust but at the moment he is only going in for one hour a week and that is a one-to-one with a lovely teacher who is trying to keep him in a learning place and at least doing something. This has left him very isolated. He would love to socialise, but can't really cope with a classroom or even the small group of six they have asked him to join. I just don't know what the right thing to do is? I know no-one can wave a magic wand but it seems a shame that there isn't a place where he can just do his art, learn in a quiet place where the pace is slower and maybe make a friend. At the moment we feel a bit stuck, just kind of hoping that things improve and when he gets used to the college maybe his confidence will grow. He does have headphones btw because noise is a big trigger, especially lots of people talking at once, but he feels self conscious and can't always hear what he needs to. Just wondered if any-one is facing a similar problem? He has ADHD and ASD.
