When my hyperactive brain damaged child had his first 5 day respite care, I nearly had a breakdown. I finally realised just how much I had been doing, on the go 24/7 with no holiday.You will be going through a "life changing moment". Expect to have an emotional roller coaster over the next few weeks as the realisation sinks in, in some ways it will be like a bereavement, which sadly I know all about. For the next few weeks, just try very hard to focus on what you have to do today, just one day at a time. Hopefully your GP will give you some support. I write a diary every evening, which I write when I've gone to bed at night. I tell the diary how I've been feeling, and anything important. It might be useful for you to do the same, then you will be able to chart your progress towards a better life. This time next year you will be in a very different place. Take care. Jill
