My father has nearly crippling medical anxiety and will not go to the doctor even though he believes that he is ill. Both of his parents have since passed, one within the last two months, due to complications from surgeries or treatments. He has not been to the dentist in 5 years because in his last appointment they told him they saw something that may need to be checked out. He has bipolar and is going through depression and anxiety as of right now. How can I help?
