Elder Care Job in Leesburg, Florida

My father is 73 years old and lives alone. He suffers from chronic pain and depression and his memory is not very good. He overdosed on prescription sleeping pills about a month ago and in June suffered a mild stroke. He needs help with his pain meds I think on a daily basis. He also needs help with light housekeeping, some meal prep and companionship. I live in Virginia and am leaving to go back home. My dad has a nice in Tampa who helps him a lot as well but we have become overwhelmed and we are scared that when I go back home, he will overdose again. He doesn't understand that he is taking pain MANAGEMENT not pain GOES AWAY INSTANTLY WITH A PILL. I contacted different in home care companies since I have been here the last week. They are expensive and require a 4 hour minimum and do not accept Medicare. Me and my cousin are at wits end and time is running out. My dad wants to try one more time to stay in his home, but he needs assistance. Can u help me?
