This won’t be exactly what you were looking for necessarily but when I read this I felt compelled to respond. Twice I have failed in my pursuits in such a way that going forward was essentially “starting over”; in both of these cases there were residual consequences such as debt. It was heartbreaking for me and I don’t know exactly what it feels like for you right now but I imagine it is a heartbreaking experience for you right now, as well. Let me tell you two things, please, based only on my experience.
First: in both cases things got better sooner than I had expected; within a few years things were good... once I had dusted myself off and applied myself to the next chapter of life, I was able to take steps, find ways to dig out, and find hope and passion again in my pursuits.
Second: I, like you, had a lot to offer the world, my profession, and my family and friends; I look back and can see these things. Please, hang in there, and please, don’t let the downturns extinguish your light. Whether you know it or not now, many people will need you around, and in the end, even more will be better off for your influence.
