Hi Jane and welcome
We too are a year down the road now, my son was diagnosed Dec 10 aged 15. The early weeks really are an emotional drain for the whole family, but it will get easier, honestly it will. It does become the whole focus of your life for a while, but over time you all begin to settle down. That's not to say that there aren't challenges thrown in your face along the way, but life really does get back to 'normal' after a little while, with just a few changes here and there.
Your son is bound to be all over the place at the moment, we have all been through that phase. Some days he will be cool, calm and accepting, other days he will become angry, or a quivering wreck and desperately need your love and support. You too will have days you are stronger than others. Don't hold it back, let your feeling go if you need to (privately from your son of course if you can).
As others have said, take whatever help is offered. It is so bewildering in the early stages for all of you. My son started fearing leaving the house after a few weeks, he had a really tough time, but with the help of a psychologist on the team got through that pretty quickly. If you feel your son needs extra emotional support, don't be afraid to ask for it.
And most definitely keep coming on here. Everyone is so friendly and helpful, you too need that emotional support and I personally have found this place wonderful. People 'get it' and you are not boring people as they know just where you are coming from. I must have bored the pants off my friends at home, so I just find it so much easier voicing concerns, and positive news on here.
Good luck, and welcome to this elusive club!
