Hey, I'm new hear but not new to family hassles. Seems that your father missed the fact that by seeing a psychdoc you ARE trying to find the cause of your depression. And that is no easy thing to do. Many people struggle with depression and anxiety for many years before they even look for help then, like me seem to never find the answer.
Just an opinion, if your dad is so feeling like a failure, could be he needs some help with problems too.
Hope things get better for you soon, BD. Best of luck with the prozac. If you give it a try just be patient it can take a few weeks to take effect. If you decide not to go with the drug therapy try talk therapy. What the hell, try both. I'd love it if you update about what's happening here. Until then ...take care
