You are hopeless, because you are temporarily purposeless, and its the lack of purpose that is depressing.
So, find a new purpose or goal. It doesnt have to be altruistic, or impactful to society, or overly impressive. Make a crazy plan for a hike/bike/ski multiday adventure for later this summer that forces you to research the route, plan the logistics and train hard physically. Or, since you have medical training, take a flyer and join a local chapter of Doctors Without Borders and throw yourself into that for a year and at least 1 trip (my grandma did something similar as a surgical nurse and spent 20 years traveling and seeing some really crazy cool parts of south america and the amazon till she was almost 80). If you cannot find fulfillment and purpose from your current situation, then find it from another source that utilizes all the skills, knowledge, wisdom, and resources that you have spent the last few decades earning and accumulating.
