My father is 75 and in fairly good health according to his doctor. He is convinced that there is something very medically wrong with him even though all of the tests have come back negative. My mom passed away about 20 years ago (he never remarried) and I'm 31 who lives about two hours away. Over the years, he's been depressed and extremely paranoid. I don't really know how to help him and I don't know what to do for him. It seems in the past few months, his depression has gotten worse. He doesn't have any hobbies or hang out with people which I'm sure makes his depression even worse. Any advice would be greatly appreciated! Thanks!
