My wonderful son, clever, funny and kind is sinking even deeper into depression. He is on medication and at uni. I have suggested counselling tonight to him which he says he has tried and it is useless. I have offered to pay to see a private counsellor. I try to let him decide what is best but I am so worried that this is not going to pass and the boy he once was will never come back. He came home over Christmas and couldn't wait to return to uni even though we are a loving family and go out socially etc. he has made friends and has a girlfriend, who is also suffering from anxiety.
