Pete,
Sorry to hear about the accident. The road to recovery will seem frustratingly slow for you. Any brain injury puts a lot of difficulties in the way of recovery. You say you have a house full of friends, helping, to look after you, and that you don't know what to do....
Let them help, roll with it, it will be frustrating, but you will need a lot of help. That said, don't be afraid to ask for some space, and time, to be on your own, and to reflect without interference, you need this just as much.
As a carer, i have worked with some brain injury sufferers, and i know that a) it can seem a long and frustrating journey, and b) you can do it.
Some things might change forever, and you have to accept that this may be the case. Sorry to say that, but it is better to be realistic at the start,
If you need to vent...vent here.We will understand, and hopefully be able to comfort, or advise.
Head up mate, you're here to tell the tale, and thats what matters....
Get well soon,
Dave
