There's a lot of great advice here on what to do. The one thing I want to add is see a doctor for your depression. It sounds like everything in your business is going well and you should be proud of yourself, yet personally you feel at the lowest point. Burn out is real and happens to most entrepreneurs who go the distance. When you get depressed, your mind focuses on negative memories and situations and you get trapped in a train of negative thought. Even though, almost every negative memory can be thought of in a positive way. There was one time where I felt like you do, and after working on my depression I was able to recognize the negative thoughts in my mind and start to look at them in a different way. Once this happened I felt like a completely new person and was able to look at the same data in a different way that made me feel empowered and hopeful. Depression will destroy you if you don't get it treated. Happiness is a conscious decision and you can recover from your burn out if you shift your perspective.
