Thankyou ever so much for all the wonderful advice. I really do appreciate all the trouble all you people go to just to help educate others. It reall is inspirational. I beleive that i will be posting in these forums for a very long time and will let you all know how i am doing. At the moment i am a very sickly 18yr old girl who is suffering from many ailments, dont want to bore you with the details. But as I start getting into the swing of things I will keep everyone informed. I actually do have some hope that all of this is the way forward. thanks again. kat xx
