i see where you are coming from now! i have not had to care for anyone to that extent yet. My husband's father is destined for a wheelchair in the next decade so I will be there at some point as there is no one else to care for him. My husband and I are already planning for that situation when it arises. His father won't want to come here to live with us but won't have any choice. So we have planned to add onto the house and get a service dog for him when the time comes. He will be of sound mind, but wheelchair bound. Maybe make yourself not so available to the children that can function without you. Sometimes a person doesn't appreciate someone until they are gone. If you can afford it, plan your vacation and go it sounds like you REALLY need it! When you get back...get your pup! God Bless!
