I'm sorry about your career - this must have been difficult to write about. Sometimes it's about the journey, take solace that you just might be in a temporary dip in your life adventure. How can some of these setbacks be opportunities?
Bad things happen to good people. There is no fairness in life or the world. Either you have impressed some rich people and are privileged to enjoy life, or you suffer because nobody fucking cares and nobody is coming to save you.
So far the only good thing to come of the current trash fire of my life is that I quit drinking alcohol. I am still a mess / wreck of a human being but at least I'm more coherent and aware of how bad everything sucks. Really makes me want to drink.
