I am so sorry to hear this. Just getting the diagnosis and being terrified and having surgery and dealing with your own feelings is bad enough, but when it happens at this time of the year and you have had plans for a great family trip which have to be shelved ... there's nothing good in this picture. I am sure you are right, your younger son is frightened of what is happening and desperate to get away from his own feelings which obviously will be powerfully confronting whilever he is at home. But it is good that he has told you that he is all right. He is probably staying with a friend ... whose parents are away? (It is terrible how many parents feel fine about abandoning their teenagers so they can go on holidays). If he makes contact again all you can do is talk to him and tell him how much you love him and how much it would mean to you - you personally, not the whole family but you specifically - if he could come home again and be with you. Probably he feels pushed out and lonely, and that nobody understands or needs him. But there is really not a lot else you can do right now except try your best to destress, and that includes asking others in the family not to stress you over this as well. Sometimes in a situation like this it is good to write a journal expressing your feelings for yourself. Often there is no-one better to talk to. I am sure others will give you support and maybe have some other suggestions. Sending you wishes and hugs. A.
