For those who was concerned about Toby Ausbun I am fine !!!!!!! Sorry to worry anyone who seen my post about my care giver, she and i are looking into getting a couple more care takers so I'm not so dependent on just having one is just better for everyone like everyone has told me that one is to much for one person to handle!!! She has been my only one for 15 yrs and I've been so blessed for that !!!!!! But time has come to ask for help and iwas having a bad morning and taking it out on her made us realize it is time to have extra help!!!!! Sorry again for worrying anybody but I know now it's way to much work all the time for one person ,thank you to those who made me realize everything !!!!!!! Thank you for your help quad list and everyone on it !!!!!! Toby.
